Abstract

The responses of 21 cultivars to downy mildew were evaluated by inoculation with conidia. Reactions were categorized into immune (0%), resistant (1-10%), moderately resistant (11-15%), moderately susceptible (16-30%), susceptible (31-50%) and highly susceptible (51-100%), based on percentage of systemically infected plants. Sporulation of the fungus increased with susceptibility and there was a direct positive correlation between incidence of infection and sporulation. Morphology of the conidia and conidiophores varied with the host genotype. The significance of these results with respect to the host-parasite reaction is discussed
