Pearl millet [Pennisetum glaucum (L.)] is the oldest cultivated crop prone to attack by many pathogens viz., Moesziomyces penicillariae, Sclerospora graminicola and Puccinia substriata. There is an urgent need to have multiple resistance against these pathogens. In order to find out economical and ecofriendly method to manage the disease; attempts were made to identify the multiple resistant sources of downy mildew, smut and rust by germplasm screening. The field screening involved artificial inoculation of hybrids, populations, inbreds and B-lines for downy mildew, smut and natural conditions are required for rust. Amongst 143 genotypes which comprised of IVT, FYT, multicut, population, inbred and B-lines, screened against downy mildew, smut and rust, under IVT genotype 197×198 showed multiple resistance whereas genotypes screened under FYT, six genotypes viz.,71×494, 131×364, 775×319, HHB223, HHB299 and HHB234 showed multiple resistance against all the three diseases. Amongst inbreds multiple resistance was observed in S-374, S-464, S-494, S-524, S-534, S-614, S-616, S-638, S-648, S-660 and S-668 and in case of B-lines genotype 72B, 74B, 76B and 47B were resistant. Amongst multicut and population genotypes none showed complete multiple resistance against downy mildew, rust and smut.
