The present investigation was conducted under laboratory conditions in the Department of Entomology, Rajasthan College of Agriculture, Udaipur during March, 2013 to June, 2014. Fifteen varieties were screened i.e. Raj-4037, HI-153, MP-1234, HI-8627, GW-366, HI-1500, KRL-1-4, HI-1544, Lok-1, MPO-1203, HD-2932, MPO-1215 and HI-1567 against Rhizopertha dominica. Minimum adult emergence (15.53 adults), longest duration of life cycle (51.33 days), lowest grain damage (22.17 per cent) and lowest weight loss (7.64 per cent) was recorded in Raj -4037, while maximum adult emergence (54.30 adults), shortest duration of life cycle (35.00 days), maximum grain damage (60.48 per cent) and maximum weight loss (22.64 per cent) was recorded in HI-1567. Out of fifteen varieties screened Raj-4037, HI-153, MP-1234, HI-8627, GW-366, MP-3288 and HI-1500 were found moderately resistant while Anuradha, 4, HI-1544, Lok-1, MPO-1203, HD-2932 and MPO-1215 were susceptible and HI-1567 was the highly susceptible variety.
