▼ Wheat is a globally traded staple crop. Wheat is important in human diets because of its agronomic adaptability, physical characteristics, functionality for the production of leavened products and nutritional value. Two significant characteristics make wheat an important staple food-crop. First, the proteins present in wheat endosperm have attributes that enable gas retention after the proteins are hydrated and mechanically worked during dough production. Second, a wider variety of products can be made out of wheat compared to other cereals. Wheat quality is defined in terms of suitability for specific end-uses. This is important for breeders, farmers, flour millers, and food producers and consumers. In the U.S. Pacific Northwest (PNW) climatic conditions favor production of soft wheat. Three soft wheat types are planted in the PNW, soft white winter (SWW), soft white spring (SWS), and club (CLUB). Batter-based products are important applications for soft wheats and include a wide range of products such as pancakes and waffles, cakes, and coatings. Pancakes are produced from fluid batters using a single step mixing process and contain sugar concentrations < 30% in their formulations. Cakes are complex food systems where their classification is based on mixing process to produce the batters and the sugar-flour ratio concentrations in their formulations. This dissertation is focused on the functionality, analysis, and selection of soft wheat quality traits that affect end-product performance and also developing a methodology to rapidly predict cake quality. The first study (Chapter 3) was concerned with the functionality of SWW wheats in pancake making. The aim of this study was to observe the differences in genotype and protein concentration on batter flow and pancake making performance of a collection of SWW wheats. Two formulations were used in the study: one based on Finnie et al (2006) called "old" and another based on the AACC-I Approved Method 10-80.01 called "new". The "new" lean formulation had an improved ability to distinguish the performance of different flours compared with the “old” as a result of wider range of pancake diameters. This study showed that pancake making performance would not be optimized by conventional superior high-quality soft wheat flours with soft kernel texture, high break flour yield, and low water-, carbonate-, and sucrose SRCs. From our results it appears that for unchlorinated flours, at least for thicker pancakes, the most appropriate flour would have higher water and sucrose SRCs and be grown under management conditions conductive to higher protein. The second study (Chapter 4) was a meta-analysis of data collected by the USDA Western Wheat Quality Laboratory (Pullman, WA). This study was done to advance understanding soft wheat quality traits that differentially affect sugar-snap cookie diameter (CODI) and Japanese sponge cake (SC) volume (CAVOL). Principal component analysis (PCA) and partial least square (PLS) regression models were used to obtain useful actionable… Advisors/Committee Members: Ross, Andrew S.

▼ Soil sulfur (S) deficiency is becoming increasingly common throughout the U.S. due to The Clean Air Act of 1990; S deficiency is typically found in high sand and low organic matter soils and looks very similar to nitrogen deficiency with stunted growth and chlorosis. Over application of N when there is a S deficiency has shown to be detrimental to wheat quality. Sulfur deficiency is detrimental to baking quality due to its effects on formation of disulfide bonds. These bonds are formed from the sulfhydryl groups of cysteine, which influence viscoelasticity of dough. Soil S deficiency can also lead to an increase of free asparagine concentration which indicates acrylamide forming potential of baked products. Acrylamide is a potential carcinogen; S fertilization has been shown to decrease acrylamide forming potential in wheat flour. Therefore, the objectives of this study were to: i) determine the effect of genotype, N, and S fertility on overall wheat quality and rheological characteristics; ii) determine the typical range of asparagine in wheat grain in Kansas: and iii) determine the influence of S availability in soils on asparagine in wheat grain. In the first study we found that in a soil with low S availability, S fertility significantly increased overall grain quality and rheological characteristics as well as increasing yield. Protein composition was evaluated by the ratio of total polymeric/ total monomeric protein using high performance liquid chromatography. In both years, the ratio of polymeric to monomeric protein was increased by sulfur fertilization. Solvent retention capacity (SRC) was evaluated using the whole grain lactic acid-sodium dodecyl sulfate solvent retention test (lactic acid- SDS SRC). In 2018, S application increased the SRC from 217% to 308%. Sulfur application increased average farinograph stability from 9.2 min to 14.6 min. Farinograph stability was effectively predicted by the SRC test (R2=0.78). Free asparagine concentration decreased significantly in both years across all genotypes when S was applied. Although, in Chapter 2 we found that poor wheat quality in a S deficient soil was increased with S fertilizer application, we did not find a strong correlation between available S in the soil and wheat quality or free asparagine concentration in Chapter 3. In 2018 a S sufficient location, Ashland had the highest free asparagine concentration (37 μmol/g) which was likely due to hot dry weather during grain fill. Thus, further investigation of factors influencing free asparagine in winter wheat is necessary for us to have a better understanding of how to decrease the risk of elevated levels. Information from this study will help winter wheat producers in the Great Plains diagnose sulfur deficiency and determine best practices for increasing grain quality and decreasing free asparagine concentration.

ENGLISH ABSTRACT: Waxy wheats are a naturally occurring genetic mutation of the hexaploid bread wheat Triticum aestivum. They contain only amylopectin starch due to the absence of the protein responsible for producing amylose, called granule bound starch synthase (GBSS). The amylopectin content retards starch retrogradation as amylopectin retrogrades more slowly than amylose. This can be utilised to increase the shelf life of bread by slowing down the staling process in which starch retrogradation is involved. One hundred percent waxy wheat cannot be used to make bread because of a resulting undesirable loaf appearance. Blends of waxy wheat and non-waxy wheats were thus used to create a loaf of bread which not only had an extended shelf life but also a desirable appearance. The starch granule morphology and percentage crystallinity of starch isolated from four waxy wheat lines (375, 376, 377 and 378), was determined using a scanning electron microscope and X-ray diffraction respectively. A non-waxy wheat control was used. No differences were seen in granule size and morphology between the lines and the control but more B-type granules were observed in control. The control was found to have an unusually high percentage crystallinity (36.5%) but was still lower than, or equal to, the waxy wheat lines (36.5 – 38%). Flour of each line was blended with the control in ratios of 10, 15, 20 and 25% waxy wheat to non-waxy wheat. Pasting properties were determined by the Rapid Visco Analyser (RVA). Blends of lines 375, 376 and 377 were found to have a lower peak viscosity, a faster peak time and a lower final viscosity than the control, while line 378 was similar in values to the control. No significant differences were seen between the blends and the control for the arrival time, water absorption, and stability as determined by the Farinograph. Likewise, no significant differences were seen for the peak time, peak height and tail height determined by the Mixograph between all blends and the control. Biaxial extension of the dough from each blend using the Alveograph showed no significant differences from the control for the P, L, P/L and W parameters. The blends were baked into loaves of bread to determine final loaf quality and shelf life. The C-Cell showed no significant differences for the cell and hole number, cell area and slice brightness between the blends and control. Lines 375 and 377 had the highest percentage concavity and therefore the worst appearance. Line 376 and 378 had the best appearance with the highest amount of waxy wheat. The texture analyser showed that waxy wheats create a softer initial loaf. On day six, only blends from line 376 successfully decreased the firmness compared to the control. The addition of up to 25% waxy wheats to non-waxy wheats marginally affects the processing properties of dough but negatively affects the outward appearance of bread. Bread baked with blends of 20 – 25% of line 376 had an improved shelf life, whilst still being visually appealing.

▼ The simple effects of nitrogen rates, fungicide application, and varietal responses on wheat yield and quality have been studied individually, but interactions among the inputs are less well understood. Traditionally, increased nitrogen rates have led to higher risk of lodging and disease severity (Roth and Marshall, 1987), but it has been found that fungicides can be used to delay the onset of disease (Gooding et al. 1999). Similarly, yield responses to application of a fungicide may be affected by available nitrogen (Olesen et al., 2003). Wheat quality parameters such as protein, test weight, and alveograph parameters may also be affected by different management systems. Recent Ontario research shows interactions between fungicide and wheat varieties, even in the absence of disease, but the relationships are poorly understood. Current field crop recommendations would be improved by knowledge of interactions between inputs in more intensive management systems. Field experiments were established on nine farm fields in southwestern Ontario to investigate possible interactions among nitrogen rates, fungicides, and varieties. Eight fungicide timing combinations were applied as splits on three N rate blocks (100, 135, and 170 kg ha-1), applied across variety strips (between three and seven) in a split-strip-plot design with three replicates. Measurements included leaf disease severity, fusarium head blight incidence and severity and mycotoxin concentrations, grain yield and yield components, protein, test weight, and alveograph parameters. An economic analysis was performed on the combinations of treatment variables toward the development of more comprehensive recommendations. Interaction between N application rate and fungicide application resulted in greater yield gains with increased N when fungicides were used. Grain protein concentration increased at higher N application rates. Revenue net of the variable costs examined was not significantly affected by N rate alone, while effect of fungicide application varied with site.

▼ ENGLISH ABSTRACT: Wheat grain kernel hardness (GKH) is one of the most important quality properties of wheat (Triticum aestivum). The molecular basis of GKH is determined by the combination of Puroindoline a (Pina- D1) and b (Pinb-D1) alleles in a wheat cultivar. The current study investigated the Pin alleles present in commercial South African (SA) wheat cultivars. Wheat production regions in South Africa are diverse; and divided into the summer rainfall irrigation (SRI) and winter rainfall dryland (WRD) regions where spring wheat is planted, as well as the summer rainfall dryland (SRD) region where facultative and winter wheat are planted. Nine commercial wheat cultivars, differing in GKH, were planted at four locations per region, with three replications, over three production seasons (2012 – 2014). After each season, the wheat grain was harvested followed by determination of kernel characteristic, milling yield, flour and dough quality properties. The Pin allele identities, of the 27 cultivars, were determined using polymerase chain reaction and allele sequencing. Four Pin allelic genotypes were identified. Wheat cultivars produced in the WRD region showed no diversity in Pin genotypes. GKH prediction models, based on the Pin allele identities of the samples, were thus developed for only the SRI and SRD production regions. Following analysis of variance (ANOVA) and Pearson’s correlations of the WRD region, where the cultivars had identical Pin genotypes, it was shown that genotype (G) primarily contributed to variation in GKH in the Swartland region. GKH correlated negatively with break flour yield (BFY), total flour yield (TFY) and α-amylase activity. Environment (E) primarily contributed to variation in GKH in the Rûens region, where GKH had negative correlations with BFY and TFY. In addition, negative GKH correlations were observed with kernel weight and diameter, and positive correlations with flour ash content, water absorption, dough strength, -stability, and -tenacity. Wheat cultivars of the SRI and SRD regions were subjected to ANOVA, with cultivars nested within Pin genotypes. Wheat containing the Pina-D1b/Pinb-D1a genotype had increased GKH, flour water absorption (FWA), dough tenacity and alveograph P/L ratio; however, decreased kernel weight, diameter, BFY, TFY, dough extensibility, -strength, -stability, and tolerance to overmixing, compared to the Pina-D1a/Pinb-D1b genotype. The Pinb-D1p mutation had decreased kernel weight, diameter, dough extensibility, and swelling index; with increased BFY and TFY, FWA, dough development time, -strength and -tenacity compared to the Pinb-D1b and Pinb-D1ab mutations. The molecular weight distribution of proteins within wheat cultivars of different Pin genotypes were determined with size exclusion high performance liquid chromatography. ANOVA with nested design and Pearson’s correlations showed environmental influence, and G x E interaction, primarily contributed to the variation in all protein fractions.

▼ Globally, wheat (Triticum aestivum L.) is the second most widely grown cereal grain and is primarily used as a food crop. To meet the demands for human consumption, cultivars must possess suitable end-use quality for release and acceptability. However, breeding for quality traits is often considered a secondary goal, largely due to amount of seed needed and overall expense of such testing. Without testing and selection, many undesirable materials tend to be advanced. Here we demonstrate two methods, mega-genome-wide association mapping and genomic selection, to enhance selection accuracy for quality traits in the CIMMYT bread wheat breeding program. The methods were developed using high-density SNPs detected from genotyping-by-sequencing and processing and end-use quality evaluations from unbalanced yield trial entries (n = 4,095) during 2009 to 2014, at Ciudad Obregon, Sonora, Mexico. Genome-wide association mapping, with covariates for population structure and kinship, was applied for each trait to each site-year individually and results were combined across years in a mega-analysis using an inverse variance, fixed effect model in JMP-Genomics. This method presents a new way to detect genes of interest within a breeding program and develop markers for selection of these traits, which can then be used in earlier generations. Genomic selection prediction models were developed using ridge regression, Gaussian kernel, partial least squares, elastic net, and random forest models in R. With these predictions genomic selection (GS) can be applied at earlier stages and undesirable materials culled before implementing expensive yield and quality screenings. In general, prediction accuracy increased over time as more data was available to train the model. Based on these prediction accuracies, we conclude that genomic selection can be a useful tool to facilitate earlier generation selection for end-use quality in CIMMYT bread wheat breeding. Genomic selection was conducted for processing and end-use quality traits in the Kansas hard red winter wheat breeding unit. Genomic predictions demonstrate increases in accuracy with added data over time. These data demonstrate that current genomic selection models will need more data to continue improvement in prediction accuracy. Advisors/Committee Members: Allan K. Fritz.

The tillage of wheat on brazilianÂs cerrado has been reaching yield amounts above the national mean. However, there is not enough information about nutriment requires of new cultivars nowadays indicated for tillage. The objective of this work was to study the conduct of wheat (Triticum spp) cultivars indicated for tillage in the state of Minas Gerais, under different levels of planting fertilization, aiming to found the best relationship of manure consumption / yield obtained and the best relationship of manure spent / rent income. The assay was realized, under regime of irrigation, in a field plot of the Cooperativa Mista dos Agricultores do Alto ParanaÃba (COOPADAP), municipal district of SÃo Gotardo - MG, in randomized blocks design and 5 x 5 factorial arrangement, with four replicates. Five cultivars (BRS 207, IAC 289, IVI 931009, 98222 and Ãgata) and five levels of fertilization (0%, 50%, 100%, 150% and 200% of the recommended level) were evaluated. The results obtained let to conclude that only the yield were affected by the different levels of fertilization, and it had been increased not in a proportional way according to the crescent levels of fertilization; the absence of fertilization promoted the best relationship of manure consumption / yield obtained and the best relationship of manure spent / rent income; due to its genotype, Ãgata cultivar presented superior in well formed grains per ear ratio, average weight of thousand grains, hectoliter weight and yield; all cultivars evaluated presented as good options for irrigated tillage of wheat in the Brazil Central Region, with yields of 1,6 to 1,9 turns above the national mean, and lodging resistance.

▼ Wheat (Triticum aestivum L.) has unique properties that allow for a variety of end products, such as pan bread, steamed bread, cookies, cakes, and tortillas. Most wheat-breeding programs focus on increasing yield and yield-related traits as primary objectives. However, end-use quality is also crucial as quality characteristics influence grain sale price and market success of a variety. Large-effect quantitative trait loci (QTL) have been identified for quality related traits. The Glu-1 loci encoding high molecular weight glutenin subunits (HMWGS) have a major effect on dough mixing properties. However, many quality traits are too complex to be controlled by only a small number of loci. These traits may benefit from genomic selection (GS), which utilizes all effective loci regardless of effect size. Genomic selection can accelerate genetic progress especially for traits that are costly or time consuming to phenotype, like quality-related traits. This research focused on the genetic improvement of end-use quality in hard winter wheat by targeting specific loci with known effects or by using all loci in a GS approach. The objectives of this study were to: i) evaluate agronomic and quality effects associated with different combinations of HMW-GS at the Glu-B1 and Glu-D1 loci among a set of near isogenic lines (NILs); ii) use a genome-wide association approach to identify QTL and develop predictive models for pre-harvest sprouting tolerance (PHST) and iii) assess GS models for milling and baking traits in hard winter wheat lines representative of west-central U.S. Great Plains germplasm. A set of NILs that varied for alleles at the Glu-B1 and Glu-D1 loci were evaluated for dough mixing properties, kernel characteristics, and agronomic effects. Results confirmed the Bx7OE + By8 HMW-GS (Glu-B1a1 allele) at Glu-B1 contributed to greater dough strength compared to the common Bx7 + By8 HMW-GS (Glu-B1b allele); however, the effect was not as significant as that conferred by Dx5 + Dy10 subunits (Glu-D1d allele). Near isogenic lines with the combination of both favorable alleles at Glu-B1 and Glu-D1 had the largest mixograph mixing time. However, a decrease in yield was observed for groups containing the Bx7OE + By8 subunits. These results suggest glutenin allele combinations are useful for improving bread-making characteristics in winter wheat but some combinations may be associated with negative effects on yield. Pre-harvest sprouting (PHS) is a major problem in wheat that results in decreased yield and quality. Genomic selection was evaluated as a potential breeding method for PHST given the complex inheritance and phenotyping difficulty of this trait. In this study, genotyping-by-sequencing (GBS) markers were used to identify QTL associated with PHST among a panel of hard red and white winter wheat lines. Genomic selection models were developed with the GBS data and phenotype data collected across seven growing seasons. The effect of including identified QTL and kernel color as fixed effects in the model… Advisors/Committee Members: Haley, Scott (advisor), Morris, Craig (committee member), Poland, Jesse (committee member), Thomas, Milt (committee member).

▼ Abiotic stresses including high temperatures and moisture deficit are detrimental to bread wheat production. Under abiotic stresses, characteristics such as yield, growth rate, gene expression and quality are affected and responses might involve interaction of many genes. Most studies on the impact of abiotic stresses such as high temperatures and moisture deficit have concentrated on effects on yield and agronomic traits with less work being done on grain quality. This project focussed on the end-use quality of wheat grain produced under a range of field production conditions including high temperatures and water shortages, using two mapping populations, Gladius/Drysdale and RAC875/Kukri. Gladius, Drysdale and two pairs of backcross derivatives having Wyalkatchem and RAC1262A as recurrent parents were also studied under normal and heat stress conditions in a glasshouse experiment. Of the backcross derivatives, one line of each pair has a Gpc-B1 (high grain protein content) gene introgression and the other does not. Field trials were conducted in Australia and Mexico and the glasshouse experiment was conducted in Australia. For the glasshouse experiment, Gladius showed more heat tolerance with no significant decrease in grain weight compared to Drysdale. The backcross derivatives with the introgression segment had higher grain protein content, percentage unextractable polymeric protein and accelerated senescence than ones without the segment. Grain weight and senescence were severely affected by heat stress. Quality analysis of field grown material involved sequential assessment of grain, flour, dough and baked product characteristics. Stress conditions increased protein content, decreased yield, grain thickness, width and increased dough development time compared to the control. The exposure to heat stress resulted in an increase in loaf volume compared to the control experiment. Genetic linkage maps were constructed for the Gladius/Drysdale population and used for quantitative trait loci (QTL) analysis. Quantitative trait loci analysis detected several genomic regions associated with quality traits under a range of conditions including drought and heat stress in both populations. Some of the traits were associated with known phenology and quality genes, some QTLs detected have been reported in other studies but some QTLs were novel and had not been detected elsewhere. The novel QTLs detected under conditions involving heat and drought stress present opportunities for selection of lines that are able to maintain quality under these adverse conditions.

▼

Os parâmetros mais utilizados na avaliação da qualidade industrial da farinha de trigo são obtidos por análises viscoelásticas de farinografia, alveografia, mixografia, e número de queda (NQ). Estes métodos tradicionais apresentam boa correlação com a qualidade industrial. Contudo, são caros, difíceis de serem implementados e demandam grande quantidade de sementes. Por este motivo, a seleção para qualidade de trigo geralmente é realizada em fases mais avançadas dos programas de melhoramento genético, nas quais a quantidade de sementes é suficiente para realização dos testes. Por isso, é altamente desejável a utilização de métodos preditivos da qualidade da farinha de trigo, de baixo custo, simples de serem implementados e que demandem pequena quantidade de amostra. Isso possibilitaria maior efetividade de seleção em fases iniciais dos programas de melhoramento, onde se concentra a maior variabilidade genética. Assim, o primeiro estudo desta dissertação objetivou determinar a eficácia do método alternativo da CRS (Capacidade de retenção de solventes) em diferentes genótipos brasileiros de trigo e verificar a associação entre CRS e os diversos parâmetros de qualidade industrial do trigo. Foram utilizadas sementes provindas de ensaio de Valor de Cultivo e Uso (VCU) de 22 genótipos de trigo (10 cultivares e 12 linhagens) cultivados no ano de 2014 em duas épocas de semeadura em 4 locais da região sul do Brasil (Abelardo Luz – SC, Cascavel – PR; Guarapuava – PR e Não Me Toque – RS). Foram realizados testes convencionais de qualidade de trigo: alveografia, número de queda, análise de cor e analisados os materiais através da CRS. Os resultados demonstraram que a CRS e os parâmetros de qualidade de trigo possuem significativa interação genótipo x ambiente (GxA). Observou-se associações significativas, de média magnitude, entre a CRS e as análises viscoelasticas, demonstrando que a CRS pode ser utilizada na seleção de genótipos para qualidade de trigo brasileiro. O segundo estudo objetivou determinar a sedimentação em SDS em diferentes genótipos brasileiros de trigo e observar a correlação entre SDS e o parâmetro de força de glúten, buscando aferir a eficiência desta metodologia. Este estudo foi conduzido utilizando sementes de trigo provenientes de experimentos executados em quatro locais (Abelardo Luz – SC, Cascavel – PR; Guarapuava – PR e Não Me Toque – RS) no ano de 2014 durante duas épocas de semeadura. Foram avaliados 25 genótipos, incluindo linhagens e cultivares comerciais, em ensaios de VCU. Foram realizados o teste convencional de alveografia para obtenção do parâmetro de força de glúten (W) e o método alternativo de SDS. O parâmetro SDS foi positivamente associado (r= 0,65**) com a força de glúten (W), podendo ser utilizado como preditor na seleção de genótipos de trigo para qualidade de panificação.

The parameters most used in evaluating the industrial quality of wheat flour are obtained by viscoelastic analyzes of farinograph, alveograph, and falling number (FN). These traditional methods have a good…

▼ ABSRACT Ranking wheat flour quality by class or grade does not reveal functional quality attributes relevant to the end user. This has resulted in a continuous effort to find more effective ways to measure quality across the wheat value chain. In line with these efforts, a novel rheology instrument, the CORE, was introduced as a simple and rapid quality test for gluten. The instrument applies a biaxial compression force followed by a free recovery, to measure the elastic behavior of gluten samples. Although designed for gluten, the instrument exhibits potential to reveal valuable data using dough as a more realistic test material. The CORE was optimized for dough, resulting in new test parameters where dough is compressed at 1 Newton (N) for 5 seconds, followed by a 55-second free recovery. To gain a deeper understanding of its characterization abilities, this test was applied on three large sample sets of flour. It showed a wide range of degrees of elasticity (DE) across different wheat classes and within two sets of Hard Red Winter (HRW) wheat. In addition, the test revealed a new measureable material property, firmness, represented by a sample‟s resistance to the applied compression force (RC). This new value was strongly negatively correlated with DE, at r2=0.89, indicating that samples which are highly elastic are also difficult to compress. Values for DE and RC showed inconsistent correlations with some physicochemical data, but strong agreement with rheological data of the farinograph and alveograph, where multivariate correlations exceeded 0.80. The CORE was capable of detecting a significant increase in DE and RC upon treatment of flour with dough-enhancing enzyme transglutaminase. However, the enzyme‟s effect varied among cultivars. Similarly, the CORE was successful in detecting improved elasticity upon blending strong flour with weaker flour. Yet, the extent of elasticity imparted by the donor flour was cultivar-specific, and not mathematically predictable.

▼ Improving soil quality with the inclusion of pulse crops in wheat-based cropping systems may help producers to develop appropriate sequences for crop rotations with improved resource using efficiency. The objective of this study is to examine selected physical, chemical and biological soil quality attributes of pulse crops with shallow and deep root systems grown in wheat-based, semi-arid, rain-fed conditions. The study was conducted at Brooks, AB using field pea (Pisum sativum L.), chickpea (Cicer arietinum L.) and lentil (Lens culinaris Medikus) grown alternately with wheat. A fourth rotation treatment included lentil and chickpea alternated with wheat (lentil-wheat-chickpea-wheat). All rotations with the pulse crops were compared to continuous wheat. Soils were sampled from three depths (0-15, 15-30 and 30-60 cm) in the spring of 2017 and 2018, after six and seven years of the rotation were complete. Continuous wheat enhanced the formation of macro-aggregates (>6.35 mm) and pulse crop rotations enhanced the formation of micro and meso-aggregates (1.00-0.50 mm and 0.50-0.15 mm). All of the rotations had similar fall soil moisture, soil microbial biomass, microbial community composition, total soil carbon, nitrogen and soil organic carbon at all soil depths. On a mass basis, only about 0.5 to 1.5 % of the soil organic matter was in the light fraction organic matter (LFOM). Chickpea alternated with wheat had the highest amount of LFOM and potential mineralizable nitrogen (PMN) in both sampling years. Pulse crop rotations collectively had higher LFOM and PMN values than continuous wheat in both years. Wheat alternated with field pea had the highest 1000-kernel weight, without affecting seed yield. The inclusion of grain legumes with different rooting depths into wheat-based cropping systems did not influence overall soil quality in the short time frame of this study. However, this study provides a baseline for the evaluation of the effect of inclusion of pulse crops into wheat-based cropping systems soil quality while emphasizing the importance of the subsequent wheat crop productivity.

▼ Bu çalışmada, süne mücadelesinde kullanılan farklı alfa cypermethrin dozlarının (0, 15, 30, 45, 60 cc/da) bazı ekmeklik buğday (Gerek 79, Bezostaja-1, Bayraktar 2000) çeşitlerinde verim ve kalite üzerine etkileri araştırılmıştır. Ankara-Haymana ekolojik koşullarında 2015-2016 ve 2016-2017 yıllarında iki yıl süreyle tarla denemeleri yürütülmüştür. Araştırma sonucunda; farklı alfa-cypermethrin dozlarının ikinci deneme yılında süne emgi oranı ile Zeleny sedimantasyon değerine etkisi önemli bulunmuştur. Kontrol uygulamasında (0 cc/da) süne emgi oranı % 4 ve Zeleny Sedimantasyon değerleri 35.6 ml iken 60 cc/da ilaç dozunda emgi oranı % 1.4'e düşmüş, Zeleny sedimantasyon değeri 40.7 ml'ye yükselmiştir. Kullanılan ilaç dozlarının ölçülen diğer özelliklere etkisi iki yılda da önemsiz bulunmuştur. Çeşitlerin; birinci yılda bitki boyu, başakta tane sayısı, başakta tane ağırlığı, bin tane ağırlığı, hektolitre ağırlığı, yaş öz (gluten) oranı, düşme sayısı üzerine etkisi önemli bulunurken, ikinci yılda bitki boyu, başakta tane sayısı, başakta tane ağırlığı, birim alan tane verimi, hektolitre, yaş öz (gluten) oranı, Zeleny sedimantasyon değeri ve düşme sayısı üzerine etkisi önemli bulunmuşur. Çeşitlerin başak boyu, hasat indeksi, nem, protein oranı ve süne emgi oranı üzerine etkisi iki deneme yılında da önemsiz bulunmuştur. Çeşit*doz interaksiyonu ise sadece ilk deneme yılında un randımanı üzerine etkili bulunmuştur. Farklı alfa cypermethrin dozlarının Zeleny sedimantasyon değerine etkisinin önemli olduğu ikinci yılda süne emgi zararı da önemli artış göstermiştir. Zeleny sedimantasyon değerinin artan süne zararından mı yoksa artan ilaç dozundan mı etkilendiğinin hem tarla hem de laboratuvar şartlarında yeni araştırmalar ile test edilmesi gerekmektedir. In this study, we investigated the effect of different doses of alpha cypermethrin (0, 15, 30, 45, 60 cc/da) used in sunn pest control in some wheat varieties (Gerek 79, Bezostaja-1, Bayraktar 2000) on yield and grain quality. Field experiments were carried out for a period of two years in 2015-1016 and 2016-2017 in Ankara-Haymana ecological conditions. According to the results, the effect of different alpha cypermethrin on the rate of kernel damage and Zeleny sedimentation value was found to be significant in the second trial year. At 60 cc/da, rate of kernel damage decreased to 1.4 %, and the Zeleny sedimentation value increased to 40.7 ml while the control application (0 cc / da), the rate of kernel damage was 4 % and Zeleny sedimentation values were 35.6 ml, The effect of alpha-cypermethrin doses on other measured properties was found to be statistically nonsignificant in two years. In the first year, the effect of varieties on plant height, grains per spike, grain yield per spike, test weight, thousand kernel weight, amount of gluten and falling number were found significant and also the effect of varieties on plant height, grains per spike, grain yield per spike, test weight, grain yields per square meter, amount of gluten, Zeleny sedimentation value and falling number… Advisors/Committee Members: Güler, Mustafa (advisor).

▼ Gluten is a macro polymer responsible for the unique viscoelastic properties of wheat dough and it is formed from the interaction of wheat seed storage proteins. The low-molecular-weight glutenin subunits (LMW-GSs) are one of the major components of gluten and play a critical role in the determination of wheat end-use quality. However, a clear association between different LMW-GSs and wheat quality is not well understood. The LMW-GSs are in fact hard to differentiate both at genic and protein level. They are encoded by a multigene family located on the short arm of the homoeologous group 1 chromosomes at the Glu-3 loci. The number of LMW-GS genes in each wheat variety differs and there is evidence that genes at each Glu-3 locus are divided by large intergenic and highly recombinogenic regions. Also, LMW-GSs are highly similar in structure among themselves and with many gliadins making them difficult to differentiate at the protein level. For these reasons, the identification of different LMW-GS protein profiles has been challenging, and conflicting results on the association between LMW-GS alleles and wheat end-use quality have been reported. The objective of this project was to develop a better understanding of the genetics of the LMW-GSs and of the role that each LMW-GS gene has in the determination of wheat end-use quality. First a set of common wheat varieties identified as standards for the Glu-3 alleles were analyzed for their LMW-GS genic profile to verify whether there was an association between a specific genic profile and the relative Glu-3 allele. Then, the genetic linkage between the LMW-GS genes at each Glu-3 locus was investigated to develop a better understanding of the Glu-3 loci structure. The results obtained from the two previous analyses were used to better interpret and characterize the LMW-GS profile of a set of elite bread wheat varieties and to correlate specific LMW-GS genes to different dough rheology parameters. Finally, a set of molecular markers specific for each LMW-GS haplotype was developed to facilitate the analysis of the LMW-GSs in wheat breeding programs. Results of this project will greatly improve the current knowledge of the LMW-GSs. Advisors/Committee Members: Morris, Craig F (advisor).

▼ Hard white winter (HVVW) wheat cultivars must have superior protein quality and consistent processing quality to be successful in the Asian market. New cultivars and management strategies are needed to produce HVVW grain for both bread and noodle applications from diverse environments in the US Pacific Northwest (PNW). This study investigated the variability in grain quality, grain protein content and composition, and dough mixing properties in relation to moisture stress during grain-fill and nitrogen management in the PNW. Seven HWW and two soft white winter wheats were grown under line source irrigation and two nitrogen fertilization levels over two years and two locations. Plots were irrigated during grain-fill to replace from 100 to less than 30 % of measured evapotranspiration. Grain quality, protein quality, and protein composition were characterized by nitrogen determinations, single kernel analysis, polyphenol oxidase activity (PPO), SDS sedimentation tests, Mixograph analyses, and sizeexclusion HPLC. Water stress during grain-fill negatively affected grain yield, test weight, and kernel weight and diameter. Among HVVW cultivars, water stress caused reductions in test weight which were of larger magnitude in late maturing cultivars than in early genotypes. Mixograph peak time, stability, and tolerance were relatively unchanged over irrigation treatments. Nitrogen fertilization showed a positive contribution to both protein quantity and quality, without affecting PPO levels. Moreover, no significant correlation was found between flour protein and PPO. Changes in protein quality and composition were related to general increases in protein concentration, regardless if the result of reducing irrigation or increasing fertilization. The proportion of monomeric proteins (gliadins) increased more rapidly than the polymeric proteins (glutenins) as flour protein increased. Grouping of genotypes in biplots indicated that cultivars of similar quality responded similarly to treatment combinations in terms of protein quality and dough mixing properties. The patterns of response suggest that management strategies to meet target protein content and enduse quality are relatively independent of genotypic differences. Similar management strategies could then be recommended for HVVW when targeting specific end-uses. Early maturity reduced the impact of water and heat stress during grain-fill and would contribute to enhance grain quality and consistency in PNW cultivars. Advisors/Committee Members: Peterson, C. James (advisor), Christensen, Neil (committee member).

▼ Bread is one of the major constituents of the human diet and wheat (Triticum aestivum L.) is the most important cereal for bread making. The gluten proteins (glutenins and gliadins) are recognised as important components affecting the processing quality of wheat flour. Glu-B1al is an allele that includes a duplication of a gene encoding an x-type high-molecular-weight glutenin subunit, and is thought to increase dough strength through overexpression of that subunit. In this research, a particular glutenin subunit in an Australian cultivar, H45, was investigated. H45 seemed to carry Glu-B1al, but it has relatively low unextractable polymeric protein (UPP, an indicator of weak dough). Two Bx genes from H45 were cloned and sequenced. Their sequences differ from each other, and each differ by four single nucleotide polymorphisms (SNPs) from the sequence of the Bx genes of Glu-B1al in the Canadian wheat cultivar Glenlea. One of the SNPs leads to an extra cysteine residue in one of the subunits. The Glu-B1 allele of H45 was designated Glu-B1br. With a restriction digest assay designed to distinguish the Glu-B1br allele from other overexpression alleles, it was demonstrated that Glu-B1br is co-inherited with low UPP. Among accessions present in the pedigree of H45 and accessions carrying overexpression alleles, Glu-B1br was detected only in H45. Efforts were made to develop alternative markers for Glu-B1br. Potential polymorphic regions within or close to Glu-B1 locus were investigated, but no closely linked polymorphisms were found that could be targeted for marker design. Individual glutenin subunits encoded by overexpression alleles and a mutant gene (MutBx7.1) derived from the first gene (Bx7.1) of Glu-B1br were obtained by heterologous expression. Flour incorporation tests showed that the glutenin subunit with the extra cysteine residue (Bx7.1) affects flour and dough mixing properties differently from MutBx7.1 and from the Bx subunits encoded by other overexpression alleles. Given that Bx7.1 and MutBx7.1 differ only with respect to the additional cysteine in Bx7.1, the effects of Bx7.1 on the dough properties of H45 can be attributed directly to that cysteine, which may act by impeding polymerisation.

Duonos gamintojams be paminėtų faktorių aktualus kuo didesnis raugų stabilumas, nuo kurio priklauso technologinio proceso tolygumas ir stabili duonos kokybė. Dėl šios priežasties aktuali yra raugų stabilumo išlaikymo būdų paieška. Kepinių juslinės ir reologinės savybės, o taip pat jų išlaikymas, pokyčiai susiję su žiedėjimu bei mikrobinis saugumas priklauso nuo fermentacijos proceso ir raugų mikrofloros. Didžiausią įtaką duonos su raugais kokybei turi geros konsistencijos ir mikrobiologiškai stabilus raugas, o vienintelis būdas stabilumui užtikrinti yra PRB antimikrobinės savybės. Raugų mikroflora bei jos savybės plačiai tyrinėjamos įvairiose pasaulio šalyse, tačiau apie Lietuvos pramonėje naudojamus raugus tokių duomenų literatūroje nepavyko rasti. Vis plačiau nagrinėjamos galimybės panaudoti bakteriocinus gaminančias PRB kaip pradines kultūras augalinės žaliavos fermentavimui. PRB yra rauguose dominuojantys mikroorganizmai ir jų sintetinami bakteriocinai gali užtikrinti fermentuotų produktų stabilumą, sumažinti mikrobinį užterštumą fermentacijos metu, slopinti patogeninių mikroorganizmų bei pelėsinių mikromicetų augimą. Yra žinoma, kad fermentuotų augalinių produktų maistinė vertė kinta. Fermentuoti produktai pasižymi didesne biologine verte, nes fermentavimo metu kinta angliavandenių bei baltymų struktūra, pastarieji tampa mažesnės molekulinės masės ir geriau pasisavinami. Taip pat išlaisvinamos biologiškai aktyvios medžiagos, kurios yra komplesuose su angliavandeniais, ko... [toliau žr. visą tekstą]

This study is focused on the investigation of the production opportunities of wheat bread with defatted milled flaxseed, defatted soy flour and seeds of yellow and white lupines. These plant products have been fermented by using Pediococcus acidilactici lactic acid bacteria (LAB) sourdough (65 % humidity) and after being dried using liofilization or vacuum. The control bread samples have been prepared by using plant products as additives (5 % from total flour quantity) without special technological treatment. The performed color changes of the fermented and dried (lyophilized (- 40 °C) or dried by using vacuum (+40 °C)) plant products has been measured by using a MiniScan XE Plus spectrometer. The plant products became after fermentation lighter in both cases of drying. By using liofilization in compare with vacuum drying a higher clarity has been achieved. Also, the lyophilization process has no negative influence on the vitality of the fermented products: the most considerable increase in P. acidilactici counts 9.57± 0.16 log10 cfu g-1 and 8.65±0.22 log10 cfu g-1 were measured in samples with a moisture content of 65 % of the fermented defatted milled flaxseed and defatted soy flour, respectively. The acidification activity of LAB indicates most of the beneficial properties attributed to the fermented products. The results of the baking tests showed that in all the tested bread samples a tendency of a decrease in specific volume and the porosity of crumb by using the plant... [to full text]

▼ A study was conducted to quantify weather conditions at specific growth stages of Canadian western Spring wheat (Triticum aestivum) and relate those growing conditions to variations in wheat grade and quality characteristics and to develop pre-harvest prediction models for wheat quality using weather input data. Six Canadian western spring wheat genotypes were grown in five locations across the Canadian prairies during the 2003 and 2004 growing seasons. Intensive weather data was collected during the growing season at each location and used to calculate accumulated heat stress, useful heat, moisture demand, moisture supply, moisture use and moisture stress variables for numerous crop development stages. Grain samples were graded, milled and underwent an extensive analysis of flour, dough, and bread making quality. ANOVA indicated that genotype, environment and their interactions had significant effects on most quality parameters tested. Environmental contribution to wheat quality variance was considerably larger than the variance contribution of either genotype or GxE interaction. Using the weather and crop development stage information, significant regression equations with high regression coefficients were developed for most quality parameters using just a single independent weather variable. Multiple regression equations with even higher R2 values were developed using three complex weather variables, leading to the opportunity to predict wheat quality 2-5 weeks prior to harvest. Equally strong prediction models were developed utilizing basic weather variables which could be obtained from weather stations monitoring only daily maximum and minimum air temperature and precipitation. The development periods of planting to jointing and anthesis to soft dough were the stages most frequently exhibiting the highest correlation to wheat quality indicating weather needs to be monitored during the entire growing season to accurately predict quality. Grain quality forecast models were validated using 2005 weather and crop data. Prediction models developed from the 2003 and 2004 data required modification in order to accurately and consistently predict the grain properties in 2005.

▼ Despite recognition as key bread wheat producers in sub-Saharan Africa, for decades Ethiopia and Kenya have relied on imports to meet local consumption needs. The challenges posed by pests and diseases as exemplified by repeated attacks by the Russian Wheat Aphid, and the new highly virulent race TTKSK (Ug99) of stem rust, have been strong yield barriers. To change this trend, it is important that breeding populations that combine desirable alleles for yield, disease, and pest resistance are developed followed by selection, promotion and adoption of superior cultivars. In the first chapter of this thesis, SNP- based characterization of population structure and diversity in a comprehensive panel of 297, mainly East Africa lines are described. Four to seven subpopulations were identified largely consistent with line breeding era. The oldest East Africa germplasm was found to be most diverse based on several summary statistics. Present day germplasm including that in commercial production was associated with relatively high allelic diversity too. Methods used to detect signatures of past selection successfully identified outlier SNPs possibly under positive selection which could have played an important role in increasing the adaptive range of bread wheat in East Africa. Long range linkage disequilibrium consistent with past observations for this species, was detected and is described in chapter two. Over 50 QTL for adult plant resistance (APR) to stem, leaf and stripe rusts are reported from mixed model association mapping. Similarly, APR previously observed in the cultivar Kenya- Nyangumi was dissected leading to the detection of 15 minor QTL across all rusts. These results are presented in chapter three. In chapter four, results for high and low molecular weight glutenin subunit alleles, puroindoline proteins, grain hardness and other bread making quality-determining traits that were characterized amongst 216 Ethiopia and Kenya bread wheat lines are discussed.
