Abstract Virulence and genetic diversity were studied using 21 isolates of Sclerospora graminicola, the pearl millet downy mildew pathogen collected from major pearl millet growing areas of India. Variability for virulence was determined by inoculating a set of 10 differential hosts with the S. graminicola isolates in a greenhouse. The isolates varied for latent period(6.4 to 11 days), disease incidence(0 to 98%), virulence index(0 to 18.7)and oospore-production potential(1 to 4).
