Ten interspecific progenies of mungbean were tested for their resistance against pulse beetle, Callosobruchus chinensis L. under laboratory conditions during the year 2019-20 at Department of Entomology, Institute of Agricultural Sciences, Siksha ‘O’ Anusandhan (Deemed to be university), Bhubaneswar, Odisha. This study was conducted to screening the resistance/tolerance of 10 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 and growth index of C. chinensis on progenies. Out of 10 green gram cultivars used in the investigation, two cultivars viz., GP 74(1.04) and GP 76 (1.24) were classified as resistant entries in respect of low ovipositional preference, lowest developmental period, minimum survival, while four cultivars, MH 421 (1.27), OBGG 52(1.30), GP 75 (1.35) and OUM 11-5(1.54) were categorized as moderately resistant; three cultivars, IPM 2-14(1.68), IPM 2-3(1.69) and GP 78(1.83) as moderately susceptible and the remaining one cultivar viz., DHAULI(2.03) was grouped as susceptible entries.
