Description 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, forty parents along with five control entries were screened against three Indian populations of Sclerospora graminicola under greenhouse conditions. Among the parental lines under study, ICMP 85410-P7, LGD-1-B-10, Tift 23DB-P1-P5, H77/833-2-P5, H77/833-2, Tift 238D1, ICMB 89111-P6, 81B-P13, ICMB 01222-P1, ICMB 95333-P1, ICMB 95333-P5 and IPC 804-P4 were found to be highly susceptible (>80 % DMI) in screening against three Indigenous pathogen isolates from Gujarat (Sg445), Haryana (Sg519) and Rajasthan (Sg526), while 863B-P2, AIMP 92901-S1-183-2-2-B-P08 and AIMP 92901-S1-15-1-2-B-P03 were resistant (
