Possible associations of soluble carbohydrates with chemical desiccation and drought resistance in winter wheat

Creator:: Cerono, Julio Cesar
Abstract:: Drought is a major limiting abiotic stress influencing wheat production in many parts of the world. The erratic nature of water deficits makes breeding and selection for drought resistance deficient. In environments with late season drought stress, yield losses are usually associated with kernel abortion or reduction in kernel growth....

From germplasm development to variety release : the Oregon State University food barley experience

Creator:: Meints, Brigid M. A.
Abstract:: Barley (Hordeum vulgare L.) is one of the oldest known domesticated crops. Originally cultivated for human consumption, other end-uses have gained importance over the millennia. Barley is the fourth most important cereal crop in the world (FAO-STAT, 2011), and today it is mainly used as animal feed or malted for...

Seasonal occurrence and abundance of insect pests and natural enemies in the Columbia Basin

Creator:: Klein, Matthew L.
Abstract:: Potato (Solanum tuberosum L.) is the fourth largest food crop in the world following rice (Oryza sativa L.), wheat (Triticum spp.), and maize (Zea mays subs. mays). Potatoes arrived in the United States in the early 1600s and over the following centuries, the crop was subsequently cultivated across the country...

Breeding qualitative and quantitative traits for potatoes in the Columbia Basin

Creator:: Graebner, Ryan C.
Abstract:: The cultivated potato (Solanum tuberosum L.) is one of the world’s most important staple crops, ranked fourth after maize, rice, and wheat. While the potato’s success is due largely to its high yield, it also benefits from its broad global acceptance, and its ability to be used by the consumer...

Stripe rust resistance pyramids in barley

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...

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...

Agronomic performance of six winter wheat dwarfing sources when crossed to isogenic lines for Norin 10 Rht loci

Creator:: Pedretti, Ricardo
Abstract:: Six genetically diverse dwarfing sources of winter wheat were compared to four isogenic lines for the height reducing genes Rht₁ and Rht₂. Parents and generations through the F₃ including backcrosses to the respective parents were analyzed. Seedling response to gibberellic acid and tests for allelism for plant height were employed...

Identifying QTLs for Sustainability Traits (Disease Resistance and Malt Quality) in the Facultative/Winter 6-rowed Elite Malting Barley GWAS Panel, the TCAP FAC-WIN6

Creator:: Belcher, Araby Ruth
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...

Physiological responses of creeping red fescue to stubble management and plant growth regulators

Creator:: Meints, Paul David
Abstract:: Legislation to reduce open field burning in grass seed fields within the Willamette valley of western Oregon changed established production practices. In the creeping grasses such as Kentucky bluegrass (Poa pratensis L.) and creeping red fescue (Festuca rubra L.) non-thermal management resulted in reduced yield. Studies were conducted to examine...
