PRECISE MAPPING OF HESSIAN FLY AND STRIPE RUST RESISTANCE LOCI IN PACIFIC NORTHWEST WHEAT GERMPLASM (TRITICUM AESTIVUM L.)
(2019)Hessian fly and stripe rust are major pests of spring wheat in the Pacific Northwest and cultivar resistance is a primary breeding goal. Hessian fly (HF) infestations continue to cause significant yield losses in spring ... -
PRODUCTIVITY, ECONOMICS, AND SOIL QUALITY OF ORGANIC QUINOA CROPPING SYSTEMS IN THE PACIFIC NORTHWEST, USA
(2019)Volatile crop prices and desire for sustainability have farmers considering alternative practices to increase revenue diversity and protect soil health. Organic management is a rapidly expanding alternative to conventional ... -
EVALUATING AGRONOMIC TRAITS OF QUINOA, MILLET, AND FOOD BARLEY VARIETIES FOR ADOPTION IN RWANDA AND THE U.S. PACIFIC NORTHWEST
(2019)This dissertation comprises three research studies. The first study evaluated N and seeding rate effects on β-glucan protein content, grain yield, and agronomic and quality traits of hulless food barley in two no-till farms ... -
MOLECULAR ANALYSIS OF ABIOTIC STRESS IN LENTIL
(2018)MOLECULAR ANALYSIS OF ABIOTIC STRESS IN LENTIL (Lens culinaris Medik.) Abstract by Md Nurul Amin, Ph.D. Washington State University December 2018 Chair: Rebecca McGee Lentil (Lens culinaris Medik.) is an important legume ... -
EFFECT OF HEAT AND DROUGHT STRESS IN QUINOA (Chenopodium quinoa Willd.)
(2018)Quinoa is an Andean grain crop from South America. It is recognized due to its high nutritional value and tolerance to marginal agronomic environments. High temperature and dry environments are the primary challenges to ... -
IDENTIFICATION OF QUANTITATIVE TRAIT LOCI (QTL) FOR RESISTANCE TO SOIL- BORNE PATHOGENS FUSARIUM CULMORUM AND HETERODERA FILIPJEVI IN WHEAT (TRITICUM AESTIVUM L.)
(2018)Wheat (Triticum aestivum L.) is one of the world’s staple crops essential to global food security; however, its profitable production can be threatened by soil-borne diseases. The fungus, Fusarium culmorum, and cereal cyst ... -
MOLECULAR CHARACTERIZATION OF THE LOW MOLECULAR WEIGHT GLUTENIN SUBUNIT GENE FAMILY MEMBERS AND THEIR EFFECT ON WHEAT QUALITY
(2018)Gluten is a macro polymer responsible for the unique viscoelastic properties of wheat dough and it is formed from the interaction of wheat seed storage proteins. The low-molecular-weight glutenin subunits (LMW-GSs) are one ... -
SOIL MICROBIAL COMMUNITY RESPONSE TO OILSEED CROPS INTRODUCED IN LONG-TERM MONOCULTURE WHEAT ROTATIONS
(2018)Introduction of Cruciferous oilseed crops into monoculture wheat (Triticum aestivum L.) cropping systems has increased in the Inland Pacific Northwest. Canola (Brassica napus L.), and camelina (Camelina sativa L. Crantz) ... -
Building the genetic, agronomic and economic foundations for expansion of oat cultivation in western Washington
(2017)Oats (Avena sativa L.) are a versatile crop with diverse genetic resources. A study of population structure in a collection of oat genotypes relatively unaffected by recent breeding activity identified an under-utilized ... -
RE-IMAGINING WHEAT FOR REGIONAL MARKETS AND AGROECOSYSTEMS
(2017)The commodification of wheat and its ubiquity in food, society and agriculture belies its potential to contribute to the ecology, nutrition and economies of regional food systems. The craft and science of plant breeding ... -
DIVERSITY AND MANAGEMENT OF RUSSIAN-THISTLE (SALSOLA TRAGUS L.) IN THE DRYLAND CROPPING SYSTEMS OF THE INLAND PACIFIC NORTHWEST
(2017)Russian-thistle (Salsola tragus L.) is one of the most troublesome weed species in the low- and intermediate-precipitation dryland wheat-fallow cropping zone of the inland Pacific Northwest (PNW). High levels of morphological ... -
Breeding Barley and Beans for Northwest Washington
(2017)In western Washington, small grains and legumes are valuable to growers as rotational crops that help break disease and pest cycles and rest the soil between the more intensive cash crops such as bulbs and tubers. Because ... -
Economic and Environmental Performance of Mixed Crop-Livestock Farming Systems on the Palouse
(2017)The global trends of simplifying cropping systems and segregating livestock from cropping enterprises have generated high yields while exacerbating environmental problems globally. To examine the potential for organic and ... -
