ABSTRACT
Chickpea has to face post-harvest losses in storage due to heavy bruchid infestation. Fifteen cultivars of chickpea namely Bittle-98, Parbat, Punjab-91, Paidar-91, C-44, Noor-91, NCS-2003, CM-2000, CH-41/91, Flip 97-192C, Dasht, C-44×E-100YM, NUYT-90395, BH-73111 and CM-72 were studied for antibiosis test of Callosobruchus chinensis L. (Bruchidae: Coleoptera). Cultivars having thick, hard, wrinkled and rough seed coat were found more resistant as compared to thin, soft and smooth seed coat. For antibiosis test, the cultivars of C-44, Punjab-91, CM-72, Parbat, Bittle-98, NUYT-90395, Dasht, C-44×E-100YM and NCS-2003 were found resistant showing minimum longevity of C. chinensis with a range of 11.53 to 13.56 days. Minimum days (11.53) to 100% mortality were observed for Bittle-98 and the maximum days (16.88) were recorded for Noor-91. The minimum F1 adults (2.67) were observed in grains of Dasht and the maximum (11.46) were recorded in Flip 97-192C. The minimum days (9.16) to 100% mortality of F1 adults were observed in grains of Parbat whereas the maximum days (16.04) were recorded for Flip 97-192C. Chickpea cultivars of Punjab-91, Dasht, Bittle-98 and Parbat were found resistant against C. chinensis while Paidar-91 and Flip 97-192C were found susceptible.
