  • Factors influencing the effects of host diversity on plant disease epidemics for wheat stripe rust and potato late blight

    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...

  • Effects of host resistance on Mycosphaerella graminicola populations

    Creator:
    Cowger, Christina
    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...
