The present investigation was carried out at Research Farm, ICAR Research Complex for NEH Region Tripura centre Lembucherra Agartala (Tripura) during rabi 2012-13. The experiment comprisingP1,P2 F1, F2, Bc1P1 (B1) and Bc1P2 (B2) populations of two crosses viz., IM 9214-10 x Rachna (C-1) and IM 9214-10 x Ambika (C-2) was conducted in randomized block design with three replications. The populations were employed for the assessment of genetic variability, heritability and genetic advance for days to first flowering, number of branches per plant, days to maturity, plant height, number of clusters per plant, pod bearing length, seed setting percent, pods per cluster, number of pods per plant, pod length, hundred seed weight and seed yield per plant. Analysis of variance revealed that sufficient genetic variation has been created for seed yield and its attribute for taking different biometrical analyses. Relative magnitude of phenotypic coefficients of variation was higher than genotypic coefficients of variation for all the characters under study indicating environmental influence on the traits. High heritability coupled with high genetic advance as per cent of F1 mean was found for plant height, clusters per plant, pod bearing length, pods per plant and seed yield per plant indicating that direct selection can be effective for yield improvement in the populations under study.
