Abstract:: Stripe rust (Puccinia striiformis f. sp. tritici) and Septoria tritici blotch (Zymoseptoria tritici) are a constant and significant threat to wheat production, significantly reducing wheat quality and yield. Wheat is responsible for 20% of the world’s human calorie intake, and wheat production must increase to supply the demand of the...

Abstract:: This dissertation consists of a general introduction, three research manuscripts, and general conclusions regarding the mapping of quantitative trait loci (QTLs) for sustainability traits in the Triticeae Coordinated Agricultural Project (TCAP) facultative/winter 6-rowed elite malting barley genome-wide association studies (GWAS) mapping panel, the TCAP FAC-WIN6. The first research manuscript, a...

Abstract:: Shattering is a natural phenomenon of floret and spikelet disarticulation across abscission layers of the pedicel and rachilla, respectively, after seed maturation. Seed shattering in cool-season grasses and native grass species is an economic problem in seed production. This study was conducted to determine whether the use of the plant...

Creator:: Chen, Fu-chiang and Chen, Fuqiang
Abstract:: The production of barley (Hordeum vulgare L.) haploids by crossing with H. bulbosum is a widely used tool in breeding and genetics. Certain barley genotypes have low seed set in this interspecific cross, a phenomenon known as partial incompatibility. Haploid production efficiency and gamete sampling are important issues with the...

Creator:: Castro Tabo, Ariel Julio
Abstract:: Genetic resistance is the most appropriate way to control diseases in crop plants. Resistance can be described as qualitative (involving a gene-for-gene system) or quantitative (with continuous distribution of disease levels). The relationships between different types of resistance remain obscure, as does the genetics of quantitative traits. The use of...

Creator:: Schuppert, Gunnar Felix
Abstract:: Wildtype sunflower typically produces 12-24% oleic acid (18:1) and 70-82% linoleic acid (18:2). High-oleic sunflower, by contrast, produces up to 80-94% oleic acid. The monounsaturated oleic acid has a greater oxidative stability than the polyunsaturated linoleic acid, predominant in wildtype sunflower, and has greater nutritional benefits than polyunsaturated and saturated...

Creator:: Velloza, Theodosius Marmaduke
Abstract:: Summer drought is a major factor limiting the regrowth of perennial ryegrass seed crops. This phase of crop development has a strong influence on seed yield because most of the tillers that contribute towards next season's seed crop are produced or regrown during this period. In recent years many seed...
