The genetics of winterhardiness in barley : perspectives from genome-wide association mapping

Creator:: von Zitzewitz, Jarislav
Abstract:: Fall-planted barley makes the best use of available precipitation in the Pacific Northwest of the United States. This growth habit is also suitable to many other areas of the world. A prerequisite for production in most of these areas is tolerance of low temperature during the vegetative growth stages. Fall-planted...

Developing Flavorful and Sustainable Barley (Hordeum vulgare L.): Integrating Malting Quality and Barley Contributions to Beer Flavor within the Framework of Facultative Growth Habit

Creator:: Herb, Dustin Walker
Abstract:: This dissertation consists of a general introduction, three manuscripts, and general conclusions. The research integrates research on (1) the effects of barley genetics and production environment on the contribution of barley to beer flavor, (2) the effects of degree of malt modification on barley contributions to beer flavor and (3)...

Advancing Naked Barley: Malting Protocol Manipulation and Embryo Retention Insights

Creator:: Vallejos, Cristiana L.
Abstract:: Naked (hull-less) barley has historically been grown for food, but interest in, and breeding efforts for, its use in malting and brewing have increased due to the potential benefits: reduced off-flavors, reduced spent grain, and higher malt extract. These benefits are offset by limiting factors such as high b-glucan and...

Production of haploid plants in selected winter wheat genotypes through anther culture and intergeneric crosses with maize

Creator:: Mendoza, Maria Graciela
Abstract:: A higher level of efficiency in the production of doubled-haploids must be achieved if this procedure is to be beneficial in plant improvement. Of equal importance is the development of protocols, which are not genotypic specific and result in progeny that represent a random sample of gametes from the parental...

Possible association of grain protein content, harvest index and biological yield in winter wheat populations

Creator:: Costa, Jose Maria
Abstract:: A negative relation between grain protein content and grain yield is frequently observed in wheat (Triticum aestivum L. em Thell) i.e. as grain yield increases, grain protein decreases. It has been suggested that the inverse relation between grain yield and protein is in part the result of developing high yielding...

Farmer perspectives on the transition to organic agriculture : an Oregon study of farmer motivations and barriers

Creator:: Lloyd, Deanna M.
Abstract:: In the midst of double-digit growth in market demand for organic products, there is a lag in the growth of certified organic production in the United States. This thesis investigated the motivations and barriers farmers face when making the transition to organic agriculture. Three distinct organic farmer typologies were identified:...

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...

Estimates of genetic variability resulting from single, top, and double cross populations in durum wheat (Triticum turgidum L. var. durum)

Creator:: Abdennadher, Mourad
Abstract:: The success of a plant breeding program depends upon the availability of useable genetic diversity. Such diversity may be enhanced depending on the type of hybridization strategy employed. Segregating progenies resulting from F2 populations, a double cross, and a top cross were compared for the amount of useable genetic diversity...

Identifying Quantitative Trait Loci for Resistance Against Stripe Rust and Septoria tritici blotch in Soft White Winter Wheat

Creator:: Cobertera, David
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...
