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...

Testing the effectiveness of barley stripe rust resistance QTL detected in Mexico and the USA against a possible new race in Peru and mapping of genes conferring resistance to leaf rust and mildew in the same population

Creator:: Rossi, Carlos
Abstract:: Barley is the fourth most important cereal crop in the world because of its broad adaptation, its utility as a feedstock and for human food, and the superior properties of barley malt for brewing. Three of the most important foliar diseases of barley, on a worldwide level are: barley leaf...

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...

Monitoring and Evaluating the Susceptibility of Colorado Potato Beetle, Leptinotarsa decemlineata Say, against Insecticides in the Columbia Basin of Northeastern Oregon

Creator:: Yang, Pahoua
Abstract:: Potato (Solanum tuberosum L.) is among one of the largest and most important staple food crops in the world. One of the most productive growing potato regions is the USA is the Oregon and Washington Columbia Basin. Both states produce approximately 26% of the USA potatoes in the market. In...

Quantitative resistance to Puccinia striiformis f. sp. hordei in barley near-isogenic (BISON) lines

Creator:: Richardson, Kelley L.
Abstract:: Quantitative resistance (QR) to disease is usually more durable than qualitative resistance, but its genetic basis is not well understood. We used the barley/barley stripe rust pathosystem as a model for the characterization of the QR phenotype and associated genomic regions. As an intermediate step in the preparation of near-isogenic...

Identification of genetic factors controlling kernel hardness and related traits in a recombinant inbred population derived from a soft 3 ‘extra-soft’ wheat (Triticum aestivum L.) cross

Creator:: Wang, Guomei, Leonard, Jeffrey M., Ross, Andrew S., Peterson, C. James, Zemetra, Robert S., Campbell, Kimberly Garland, and Riera-Lizarazu, Oscar
Abstract:: Kernel hardness or texture, used to classify wheat (Triticum aestivum L.) into soft and hard classes, is a major determinant of milling and baking quality. Wheat genotypes in the soft class that are termed 'extra-soft' (with kernel hardness in the lower end of the spectrum) have been associated with superior...

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...

Identification of quantitative trait loci underlying kernel extra-softness and related traits by linkage and association mapping in wheat (Triticum aestivum L.)

Creator:: Wang, Guomei
Abstract:: Kernel hardness (KHA) is a major factor determining break flour yield (BFY) and end-use quality of common wheat (Triticum aestivum L.). Within the soft wheat class, genotypes with consistently softer grains than common soft wheat are considered to be 'extra-soft'. In addition, 'extra-soft' wheats have greater BFY than common soft...

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....
