Abstract
This study was conducted to evaluate the resistance of 15 chickpea cultivars viz., Paidar-91, C-44, Noor-91, Bittle-98, Parbat, Punjab-91, NCS-2003, CM-2000, CH-41/91, Flip 97-192C, Dasht, C-44×E-100YM, NUYT-90395, BH-73111 and CM-72 against pulse beetle. The cultivars with rough, wrinkled, hard and thick seed coat were more resistant compared to those having smooth, soft and thin seed coat. The minimum number of holes (0.80 per grain) made by pulse beetle was recorded in grains of Punjab-91 compared to the maximum of 1.77 holes per grain in Paidar-91. The maximum number of eggs (3.12 per grain) of pulse beetle was observed in Paidar-91 and the minimum eggs (0.48 per grain) were recorded in Dasht. The adults of pulse beetle fed on Paidar-91 gained the maximum weight (10.27 mg) while the minimum weight of 7.02 mg was recorded for adults fed on grains of Bittle-98. The minimum grain damage (24.35%) was recorded in Bittle-98 while the maximum of 54.46% damage was seen in Flip 97-192C. The minimum grain weight loss of 25.66% was recorded for Dasht compared to the maximum weight loss (39.48%) in CM-2000. The minimum adults (2.96) of pulse beetle were attracted towards Parbat grains and the maximum of 5.07 adults were recorded in grains of Flip 97-192C. Chickpea cultivars of Punjab-91, Dasht, Bittle-98 and Parbat were resistant against pulse beetle while Paidar-91 and Flip 97-192C were found susceptible.
