Abstract
Twenty-eight wheat cultivars were screened for their resistance to khapra beetle, Trogoderma granarium , through no choice progeny test conducted under uniform temperature, relative humidity and grain moisture. The mean number of progeny beetles per 20 grains of the different cultivars ranged from 10.0 to 36.9. Kalyansona, HS 240, WTN 50 and UAS 2023 were the most resistant, while MACS 2846, Sonalika, Raj 6062, DT 46 and GW 1188 were the most susceptible to the storage pest. Correlation studies between various grain characteristics and progeny beetle emergence revealed that grain size and hardness played a role in resistance and susceptibility of wheat grain against khapra beetle. The maximum percentage of loss in weight was recorded in MACS 2846 (63.6) and minimum in Kalyansona (19.6)
