Abstract:
A total of 62 pearl millet entries were evaluated against downy mildew. Among sixty two entries, thirty six entries viz., BIB-7, BIB-19, BIB-20, RIB-192, RIB-15 076, RIB 525-2, J-2290, J-2340, RIB-16 5112, RIB-9215, RIB-16 5126, RIB-16 5134, RIB-16 5136, RIB-11133, RIB-11483, RIB-16 5162, RIB-16 5170, RIB-16 5186, RIB-12256, RIB-16 5196, RIB-16 5204, RIB-16 5212, RIB-16 5214, RIB-16 5216, RIB-16 5222, RIB-16 5226, RIB-16 5236, RIB-16 5240, RIB-16 5246, RIB-16 5252, RIB-16 5256, RIB-16 5258, RIB-16 5262, RIB-16 5264, RIB-16 5266, RIB-16 5152 were expressed highly resistant (PDI, 0-5%) reaction against downy mildew disease with the lowest per cent disease incidence; while, the seven entries showed resistant (PDI, 5.1-10%) reaction viz., ST-I-9, RIB-494, RIB-3135 18, RIB-13 5071, H-77 1833-2, RIB-16 5128, RIB-16 5270 Fourteen entries exhibited moderately resistant (PDI, 10.1-20%) reaction viz., BIB-3, BIB-5, BIB-8, BIB-14, BIB-16, RIB-15 076 (Tall), RIB-15 5147, RIB-15 0148, RIB-16 5114, RIB-11006, RIB-16 5146, RIB-16 5148, RIB-11487, RIB-16 5178. Five entries were recoded susceptible (PDI, 20.1-50%) to Sclerospora graminicola downy mildew viz., BIB-6, BIB-9, BIB-12, RIB-15 5137, RIB-16 5150. Most of the entries expressed downy mildew 0-5 per cent where the susceptible check (7042 S and Nokha Local) showed 100 per cent downy mildew incidence at the location. None of the entry was found highly susceptible.
