Creator:: Garrett, Karen A.
Abstract:: Most studies of plant disease epidemiology have focused on epidemics in host populations composed of a single genotype. But crop plant diversity can be a useful means of improving the deployment of resistance genes. In a series of experiments with wheat stripe rust and potato late blight, we studied factors...

Abstract:: Mycosphaerella graminicola (anamorph Septoria tritici) causes Septoria tritici blotch, a globally important disease of winter wheat. Resistance and pathogenicity generally vary quantitatively. The pathogen reproduces both sexually and asexually, and the pathogen population is highly genetically variable. Several unresolved questions about the epidemiology of this pathosystem are addressed by this...

Creator:: Cowger, Christina
Abstract:: Cephalosporium stripe of wheat (Triticum aestivum), caused by the soilborne fungus Cephalosporium gramineum, results in significant yield reductions in dryland winter wheat crops of the U.S. Pacific Northwest. The development of resistant cultivars offers the best hope for disease control. Breeding for resistance is hampered by the long trial times...

Creator:: Clark, Deborah Ann, 1954-
Abstract:: Field microplot studies conducted over two seasons (1982-1984) evaluated the influence of four physically and chemically diverse soils collected from Pacific Northwest wheat fields on the incidence of dwarf bunt of winter wheat caused by Tilletia controversa Kuhn. These soils were placed at Flora and Pendleton, Oregon to determine the...
