Abstract: The present investigation was conducted for the screening of rice germplasm against Angoumois grain moth, [S. cerealella (Oliv.)] taken up under entomological laboratory of Department of Entomology, N.D.U.A.&T. Kumarganj, Faizabad (Uttar Pradesh) during 2013-2014. There were significant differences observed indifferent rice genotypes against S. cerealella on the basis of grain damage percent. The genotypes under studies were categorized as follows- All 20 tested genotypes were found highly tolerant (<5%) up to 60 days of storage. 120 days, 3 genotypes viz. NDR-80 (3.20%), NDR-97(3.23%), NDR-359 (4.23%) were found to be highly tolerant and 17 genotypes i.e., BPT-5204 (5.23%), Bardan (5.23%), NDR-1 18 (5.26), MTU-7029 (5.28%), Narendra usar-3 (5.50%), Narendra sona (5.60%), Sahbagi (5.65%), Pusa basmati (5.68%), NDR-3 I 12, Narendra usar dhan-2009(6.23%), Narendra usar-2 (6.40%), Narendra usar dhan-2008 (6.42%), Jallahari (6.505), Shusk samrat (6.60%), Srju-52 (6.80%) and Lalmati (7.20%) were tolerant- (6 to 10%). At 180 days, 14 genotypes viz., NDR-80 (6.43%), NDR-97 (7.20%), Narendra song (7.40%), Narendra usar-3 (7.43%), NDR-359 (8.25%), NDR-2064 (8.50%), NDR-118 (8.60%), NDR31 12 (8.80%), Narendra usar dhan-2008 (8.90%), Shusk samrat (9.20%), BPT-5204 (9.00%), Jallahri (9.56%), Pusa basmati (9.65%) and Bardan (9.96%) were found tolerant whereas 6 genotypes viz., Sarju-52 (10.20%), Narendra usar-2 (10.43%), Sahbhagi (10.36%), Narendra usar dhan-2009 (10.43%), MTU-7029 (10.55%) and Lalmati (11.20%) were susceptible (11 to 25%). Grain damage showed significant positive correlation with moisture content, the number of emerged adults and weight loss in grain and significant negative correlation with germination.
