Abstract:
Ten interspecific progenies of mungbean were tested for their host preference of pulse beetle, Callosobruchus chinensis (Linn.) (Coleoptera: Bruchidae)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 resistant or tolerance of these cultivars against pulse beetle. The cultivars with small, rough, wrinkled, hard and thick seed coat were show more resistant to those having smooth, soft and thin seed coat. There were significant differences among the interspecific progenies in terms of seed infestation and weight loss caused by C. chinensis on progenies. Considering the overall mean seed damage at different days of storage period, GP 74(15.40%) recorded lowest seed damage followed by GP 76(15.78%), MH 421(16.18%), OBGG 52(16.70%), GP 75(17.13%), OUM 11-5(17.85%), IPM 2-14(18.33%), IPM 2-3(18.75%), GP 78(19.35%), and DHAULI (20.10%) in order of their susceptibility. The order of susceptibility from lowest to highest in overall mean seed weight loss (%) in cultivars were GP 74(19.73%), GP 76(21.38%), MH 421(22.28%), OBGG 52 (23.05%), GP 75 (24.10%), OUM11-5(25.15%), IPM2-14 (25.70%), GP78 (26.28%), IPM 2-3(26.73%) and DHAULI (29.14%).
