OAR@ICRISATInfluence of Host Genotype on Uredospore Production and Germinability in Puccinia arachidis.PSubrahmanyamauthorDMcDonaldauthorP VSubba RaoauthorUredospore production by Puccinia arachidis was studied on inoculated detached leaves of one susceptible and five resistant genotypes of peanut (Arachis hypogaea). Significantly fewer uredospores were produced per unit leaf area and per unit pustule area on the resistant than on the susceptible genotypes. Germinability tests carried out on uredospores from three susceptible, one moderately resistant, and 15 resistant genotypes showed that uredospores from resistant genotypes had significantly lower germinability than those from the moderately resistant and the susceptible genotypes. The significance of uredospore production and germinability in relation to resistance is discussed.Groundnut1983American Phytopathological SocietyArticle
