Downy mildew caused by Sclerospora graminicola (Sacc.) Shroet. is a major biotic constraint to pearl millet production in the semi-arid tropics. The pathogen is heterothallic and frequent recombination leads to evolution of new virulent populations. Identification of resistance to new virulent isolates is a prerequisite for resistance breeding. In the present investigation, 295 RILs along with five control entries were screened against three Indian populations of Sclerospora graminicola under greenhouse conditions. Among the RILs under study, 19 RILS were found to be highly susceptible (>80 % DMI) in screening against Indigenous pathogen isolates from Gujarat (Sg445) and Haryana (Sg519), 17 RILS were found to be highly susceptible (>80 % DMI) in screening against Indigenous pathogen isolates from Gujarat (Sg445) and Rajasthan (Sg526), and there are no RILs found to be susceptible against three isolates. Among all the mapping populations, 13 RILs were resistant (<10% DMI) to three test isolates. Remaining RILs exhibited different levels of DM incidence to pathogen - isolates.
