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...

Changes in grain quality and grain protein composition of winter wheat cultivars under different levels of soil nitrogen and water stress

Creator:: Saint Pierre, Carolina
Abstract:: 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...

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...

Association between dehydrin proteins and drought stress tolerance in seven wheat cultivars adapted to the Pacific Northwest of the USA

Creator:: Lopez, Cesar
Abstract:: The Pacific Northwest (PNW) is an important region for winter wheat production in the USA, where water deficits are often present at sowing and during grain filling. Consequently, improving the genetic adaptation of wheat cultivars to drought stress represents one of the main objectives in breeding programs. An observed biochemical...

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....

Influence of nitrogen fertilization management on the bread making quality of different wheat genotypes

Creator:: Derényi, Marina Castro
Abstract:: Breadmaking quality is an important criterion in breeding and development of hard wheat (Triticum aestivum L.) cultivars. Improvements in N management are needed to produce superior quality grain and satisfy market demands for protein content. Field experiments with three hard red and two hard white spring wheat cultivars were conducted...

Nuclear and chloroplast diversity of Pacific Northwest wheat (Triticum aestivum) breeding germplasm

Creator:: Edwards, Melanie Love
Abstract:: Wheat breeders must effectively maintain and manage existing genetic diversity in order to continue the development of superior genotypes. It is therefore fundamental that the genetic relationships and diversity within the germplasm pools be thoroughly characterized and understood. Recently, DNA-based markers have provided powerful tools for genetic diversity analysis. This...

The relationship of protein composition to end-product functionality of hard white wheat

Creator:: Gehlhar, Sarah Bronwen
Abstract:: Improving quality of hard white wheat (HW) cultivars in the Pacific Northwest is important to expand exports to Asia. Asian food processors prefer HW grain that can satisfy an array of baking needs, as well as produce superior quality noodle products. Three experimental populations were developed from single cross and...

Glutenin macropolymer in salted and alkaline noodles and its relation with dough properties and cooked noodle texture

Creator:: Ong, Yee-Ling
Abstract:: Glutenin protein molecules can form a large "macropolymer" which forms the elastic component of the gluten complex in wheat flour doughs. Little work has been done to investigate relationships between glutenin macropolymer (GMP) and noodle processing. GMP was isolated from flour of 4 wheat varieties; 3 hard- and 1 soft-grained...

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....
