abstract
Twenty one interspecific progenies of mungbean were tested for their resistance against pulse beetle, Callosobruchus chinensis L. under laboratory conditions during the year 2017-18 at Department of Entomology, Agril. Research Station, Badnapur, Vasantrao Naik Marathwada Krishi Vidyapeeth Parbhani. This study was conducted to screening the resistance/tolerance of 21 interspecific progenies of mungbean against pulse beetle. The cultivars with small, rough, wrinkled, hard and thick seed coat were more resistant compared to those having smooth, soft and thin seed coat. There were significant differences among the interspecific progenies in terms of number of eggs laid, development period, adult emergence, seed infestation, weight loss and growth index of C. chinensis on progenies. Out of twenty one interspecific progenies viz., BWUC 5-1-17-1-1-7, BWUC 6-1-1-Plant, BWUC 5-1-17-1-17, BWUC 5-1-8A-2-1 and BWUC-5 progenies were found to be tolerance against pulse beetle in respect of lowest ovipositional preference, shortest developmental period, minimum adult emergence, weight loss and survival and seed infestation as compared to check. While, the progenies viz., BWUC 71-5-1-3-1, BWUC 22-1-6-1-1,BWUC-4, BWUC-3 and check- BM 2003-2 were highly susceptible to pulse beetle in respect of above parameters.
