Effect of scald (Rhynchosporium secalis) on yield and yield components of twelve winter barley (Hordeum vulgare) genotypes

Creator:: Zencirci, Nusret
Abstract:: The effects of scald epidemics, induced by Rhynchosporium secalis (Oud.) Davis, on the yield and quality of winter malting barley have not been reported. The principal objective of this investigation was to assess yield and quality losses in resistant and susceptible winter barley genotypes in diverse environments of the Pacific...

Lodging control and yield enhancement in Morex spring barley with paclobutrazol treatment

Creator:: Morrison, Laura A.
Abstract:: Lodging in cereals can cause significant decreases in yield. It is both a problem in susceptible cereal cultivars with a tall-stemmed, weak-strawed growing habit and in lodging-resistant cereal cultivars when they are grown under high-nitrogen, high-moisture regimes. Plant growth regulators (PGR's) are chemical growth retardants that offer a method of...

Inheritance of resistance to barley yellow dwarf virus disease in barley

Creator:: Sieveking, William Earl, 1932-
Abstract:: Studies were conducted on artificially infected susceptible and resistant barley varieties in an attempt to determine the effect of barley yellow dwarf virus on the growth and development of these plants. A resistant and a susceptible variety were infected at four stages of growth and harvested at two stages. Roots,...

Mapping and introgression of disease resistance genes in barley (Hordeum vulgare L.)

Creator:: Toojinda, Theeryut
Abstract:: Molecular tools, coupled with unique germplasm stocks and rigorous phenotyping, are useful for developing a better understanding of qualitative and quantitative disease resistance genes in plants. The identification of molecular markers linked to all types of resistance genes provides opportunities for implementing a range of resistance breeding strategies, ranging from...

Biology studies of Macrosiphum avenae (Fabr.), Acyrthosiphon dirhodum (Walker), and Rhopalosiphum padi (L.) on Gramineae in western Oregon

Creator:: Greene, Gerald L.
Abstract:: Field biology studies of three grain aphids, Macrosiphum avenae (Fabr.), Acyrthosiphon dirhodum (Walker), and Rhopalosiphum padi (L.) were conducted near Corvallis, Oregon, from 1961 to 1964. Populations of M. avenae were found on grain plants, and alatae entering spring barley may have been from wheat fields. Specimens were found more...

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...

FR‐H3 : a new QTL to assist in the development of fall-sown barley with superior low temperature tolerance

Creator:: Fisk, Scott P.
Abstract:: Fall-sown barley will be increasingly important in the era of climate change due to higher yield potential and efficient use of water resources. Resistance/tolerance to biotic and abiotic stresses will be critical. Low temperature is an abiotic stress of great importance. Resistance to barley stripe rust (incited by Puccinia striifomis...

Analysis of genetic resistance to barley stripe rust (Puccinia striiformis f. sp. hordei)

Creator:: Prehn, Doris A.
Abstract:: Stripe rust (Puccinia striiformis f. sp. hordei) is a serious disease of barley that can cause up to 70% yield loss in susceptible varieties. The fungus is moving northward, threatening major barley production areas in the US, where most cultivars are susceptible. Fungicides are available for control of stripe rust,...
