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...

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...

Exploiting Hordeum vulgare subsp. spontaneum genetic resources : diversity analysis and germplasm development

Creator:: Matus, Iván Ariel
Abstract:: Wild barley (Hordeum vulgare subsp. spontaneum) could be a source of useful genes for improving cultivated barley. The useful genes present in Hordeum vulgare subsp. spontaneum may be new alleles at described loci, or these may be entirely new genes in the sense that there is limited allelic variation at...

Breeding for bruchid resistance in common bean (Phaseolus vulgaris L.) : interspecific introgression of lectin-like seed proteins from tepary bean (P. acutifolius A. Gray), genetic control and bruchid resistance characterization.

Creator:: Kusolwa, Paul Mbogo
Abstract:: Interspecific hybridization was initiated between wild P. acutifolius accession G40199 and P. vulgaris to introgress resistance to Acanthoscelides obtectus (bean seed weevil). F1 interspecific hybrids were recovered by embryo rescue and maintained until flowering. Mostly sterile hybrids were backcrossed twice to common bean cultivar ICA Pijao to recover sufficient fertility...

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...

The relationship of protein composition to end-product functionality of hard white wheat

Creator:: Gehlhar, Sarah Bronwen
Abstract:: Improving quality of hard white wheat (HW) cultivars in the Pacific Northwest is important to expand exports to Asia. Asian food processors prefer HW grain that can satisfy an array of baking needs, as well as produce superior quality noodle products. Three experimental populations were developed from single cross and...

Genetics of low erucic acid and cytological analyses of wide hybrids in meadowfoam

Creator:: Gandhi, Sonali Dilip
Abstract:: Cultivated meadowfoam (Limnanthes alba Benth.) is an annual oil seed crop native to southern Oregon. California and British Columbia. The genus Limnanthes is composed of nine species and divided into two sections, Inflexae and Reflexae. The seed oil of meadowfoam is a rich source of erucic acid and several novel...

Sensitivity of wheat genotypes to a toxic fraction produced by Cephalosporium gramineum and correlation with disease susceptibility

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...

Marker development, genome mapping, and cloning of candidate disease resistance genes in sunflower, Helianthus annuus L

Creator:: Gedil, Melaku Ayele
Abstract:: The level of polymorphisms of many biochemical and DNA markers are low in cultivated sunflower (Helianthus annuus L.). The number of mapped public DNA markers is limited. Molecular markers have not been developed for the most important diseases of sunflower, such as downy mildew. The objectives of this study were...

Seed protein and chromosome number analyses of experimental wheat x jointed goatgrass (Aegilops cylindrica Host) hybrid derivatives

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...
