Creator:: Rahman, Mahfuzur
Abstract:: Cephalosporium stripe, caused by the soil-borne ascomycete Cephalosporium gramineum, is becoming an increasingly important disease of winter wheat (Triticum aestivum) in several areas of the world, especially where stubble mulch is practiced to maintain soil moisture and prevent erosion. As cultural control of the disease is infeasible and no fungicides...

Creator:: Crémieux, Lis︡ele
Abstract:: The occurrence of seed-producing wheat x jointed goatgrass hybrids in infested wheat fields suggests the possibility of gene flow between the two species. This study investigates 'Madsen' wheat x jointed goatgrass F₁ and reciprocal backcross derivatives produced in experimental field plantings. Electrophoresis of the high molecular weight (HMW) glutenin seed...

Creator:: Cannon, Joshua B.
Abstract:: Jointed goatgrass (Aegilops cylindrica Host.) is a serious weed problem in wheat (Triticum aestivum L.) production in the United States. Studies were conducted to determine the outcrossing rate, competitive ability, and effectiveness of certain control practices on jointed goatgrass. A field study was conducted over two years at four locations...

Creator:: Hass, Catherine G.
Abstract:: Tocopherols are plant secondary metabolites that are known collectively as vitamin E. Tocopherol compounds act as potent antioxidants by quenching free radicals and protecting fatty acids from oxidative damage. In humans (in vivo) tocopherols protect membrane lipids from breaking down, while in oils (in vitro) tocopherols protect fatty acids from...

Creator:: von Zitzewitz, Jarislav
Abstract:: Vernalization - the requirement of a period of low temperature to induce the transition from a vegetative to a reproductive state - is an evolutionarily and economically important trait in the Triticeae. The genetic basis of vernalization in barley (Hordeum vulgare subsp. vulgare), a model crop for the Triticeae, was...

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...

Creator:: Barrett, Miles Andrew
Abstract:: Sclerotinia sclerotiorum (Lib.) de Bary is a necrotrophic pathogen capable of causing white mold, a severe disease in common bean. White mold is of particular concern to the Oregon snap bean processing industry, where processors allow less than 3% incidence in harvested shipments. Breeding for white mold resistance in beans...
