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 comprising F1, F2, Bc1P1 (B1) and Bc1P2 (B2)', (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 in the detection and estimation of genetic parameters 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 utilizing the models suggested by Mather (1949) and Hayman (1958). Analysis of variance revealed that sufficient genetic variation has been created for seed yield and its attributes 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. Association studies show positive relationship of seed yield with all the attributing traits except pod length and hundred seed weight, where it was inconsistent in both the crosses. Days to flowering, plant height, clusters per plant, seed setting per cent and pods per cluster had significant positive association with seed yield, indicating that major emphasis should be given on these component characters for improving seed yield in the populations of pea, under improvement.
