  • Effect of wheat cultivar mixtures on populations of Puccinia striiformis races

    Creator:
    DiLeone, Julie A.
    Abstract:
    This study quantified the frequency of simple versus complex races of Puccinia striiformis Westend. in mixtures of wheat cultivars possessing different race-specific resistance genes. A simple race of a pathogen can infect only one component, and a complex race of the pathogen can infect two or more components of an...

  • Cephalosporium stripe of wheat : seedling-based resistance screening and pathogenic variability

    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...
