The total of 115 germplasm of pearl millet were screened against the highly susceptible check 7042S in sick fields. Among one hundred fifteen entries, three entries viz., MH 2466, MH 2504 and Dhanshati were expressed highly resistant (0-5%) reaction against downy mildew disease with the lowest per cent disease incidence; while, the sixty seven entries showed resistant (5.1-10%) reaction viz., MH 2458, MH 2459, MH 2460, MH 2461, MH 2462, MH 2463, MH 2467, MH 2468, MH 2470, MH 2472, MH 2473, MH 2474, MH 2477, MH 2480, MH 2481, MH 2482, MH 2483, MH 2484, MH 2485, MH 2486, MH 2489, MH 2491, MH 2493, MH 2494, MH 2495, MH 2498, MH 2500, MH 2503, MH 2505, MH 2506, MH 2512, MH 2513, MH 2517, MH 2518, MH 2519, MH 2520, MH 2521, MH 2523, MH 2525, MH 2526, MH 2528, MH 2529, MH 2530, MH 2531, MH 2533, MH 2535, MH 2539, MH 2540, MH 2541, MH 2542, MP 596, MP 599, MP 600, RHB 177, HHB 67 Improved, HHB 272, MPMH 17, 86M01, PB 1705, KBH 108, MP-7792, Kaveri S. Boss, NBH 4903, ICMV 221, Pusa Comp. 383, Pusa Comp. 701 and Pusa Comp. 612. Forty five entries exhibited moderately resistant (10.1-20%) reaction viz., MH 2457, MH 2464, MH 2465, MH 2469, MH 2471, MH 2475, MH 2476, MH 2478, MH 2479, MH 2487, MH 2488, MH 2490, MH 2492, MH 2496, MH 2497, MH 2499, MH 2501, MH 2502, MH 2507, MH 2508, MH 2509, MH 2510, MH 2511, MH 2514, MH 2515, MH 2516, MH 2522, MH 2524, MH 2527, MH 2532, MH 2534, MH 2536, MH 2537, MH 2538, MP 595, MP 597, MP 598, MPMH 21, PRATAP, NBH 5767, 86M86, Raj 171, JBV 2, ICMV 155 and ABV 04. The susceptible check (7042 S and Nokha Local) showed above 90 per cent downy mildew incidence at the location. None of the entries were found susceptible and highly susceptible to Sclerospora graminicola downy mildew
