Evaluating Field Production Issues by Investigating Grain Dormancy and Plant Segregation Patterns in Soft White Winter Wheat

Creator:: McCarthy, Christy A.
Abstract:: Wheat (Triticum aestivum) is a highly valuable crop that makes up a large portion of the world’s food. However, breeding for improved varieties with desirable characteristics can be a challenge. This research examined two different issues wheat breeders deal with throughout the selection process all the way to production of...

Multi-location analysis for the identification of quantitative trait loci underlying disease resistance against Cephalosporium gramineum and Puccinia striiformis f. sp. tritici by linkage mapping in wheat (Triticum aestivum L.)

Creator:: Vazquez, Maria Dolores
Abstract:: Wheat (Triticum aestivum L.) is one of the major crops produced in the U.S. Pacific Northwest, a region known for its wheat production for international export. Wheat production in the region is threatened by diseases such as Cephalosporium stripe and stripe rust. Cephalosporium stripe is a vascular wilt disease of...

Molecular mechanisms underlying the high oleic acid phenotype in sunflower

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...

Breeding tools for Cuphea : An updated genetic linkage map and fatty acid mutant candidate gene analysis

Creator:: Powers, Carol Anne
Abstract:: Medium chain fatty acids (MCFAs) are important industrial feedstocks for soaps, detergents and surfactants. Interspecific lines derived from Cuphea lanceolata and Cup hea viscosissima are being domesticated as a temperate source of MCFAs. These species also serve as model organisms for understanding the biosynthesis of MCFAs in seeds. Various markers...

Physiological, Chemical and Genetic Studies in Meadowfoam (Limnanthes alba)

Creator:: Zhang, Jun
Abstract:: Meadowfoam (Limnanthes alba) is an oilseed crop with unique chemical characteristics. The ability to identify physiological maturity (PM) and harvest maturity HM of the crop would permit timely harvest of high quality seeds. However, changes of oil contents, fatty acid profile and glucosinolate contents, as well as seed quality during...

Quantitative trait loci mapping of yield, its related traits, and spike morphology factors in winter wheat (Triticum aestivum L.)

Creator:: Gaynor, Robert C.
Abstract:: Increasing grain yield in wheat (Triticum aestivum L.) is a challenging task, because yield is a complex trait controlled by many genes and highly influenced by environmental factors. The genetic control of yield components and other traits associated with yield may be less complex and thus more manageable for breeding....

Genetic factors that provide adult plant resistance against Puccinia striiformis f. sp. tritici to wheat cultivar 'Stephens' in a multilocation analysis.

Creator:: Vazquez, Maria Dolores
Abstract:: Stripe rust (Puccinia striiformis f. sp. tritici) has been receiving increased attention in the USA since the appearance of more virulent races detected in the past decade. These races caused yield losses even in areas where the disease previously was rarely detected. Host plant resistance is the most cost effective...

Introgression and Evaluation of Wheat (Triticum aestivum L.) Conferring Resistance to Quizalofop-p-ethyl Herbicide

Creator:: Richter, Colette M.
Abstract:: Wheat (Triticum aestivum L.) is one of the most important crops in the world supplying about 18.8 percent of the world's caloric energy supply and 20 percent of the world's protein. In the Pacific Northwest (PNW), over one million hectares of wheat are grown every year. Wheat production is typically...

Nitrogen management and variety selection for dryland production of hard red winter wheat in northeastern Oregon

Creator:: Jepsen, Daniel R.
Abstract:: Proper nitrogen (N) management and variety selection are important for profitable hard red winter (HRW) wheat production in the dryland growing regions of northeastern Oregon. In these dryland systems, N management for grain yield and grain protein concentration (GPC) is challenging due to climatic and year-to-year variation in production environments....

Phenotypic response and quantitative trait loci for resistance to Cephalosporium gramineum in winter wheat

Creator:: Quincke, Martin C.
Abstract:: Cephalosporium stripe (Cephalosporium gramineum) is an important disease limiting adoption of conservation tillage practices in the Pacific Northwest. The disease can cause severe loss of grain yield and quality in winter wheat (Triticum aestivum L.). Modified cultural practices can reduce disease incidence, but are not always dependable because of variation...
