Abstract: The present investigation is carried out with 65 treatments (50 F₁s + 15 Parents) in RBD to find out genetic variability, heritability and genetic advance percent of mean. Analysis of variance for the design of experiment revealed that mean squares due to treatments were highly significant for all the eleven characters studied, while mean squares due to replications were found non-significant in both timely and late sown condition. The high estimates of PCV and GCV (>20%) were recorded for seed yield per plant, 100 seed weight, secondary branches per plant, and biological yield per plant and moderate estimates (10-20%) were recorded for pods per plant and harvest index in both environments. The high estimates of heritability in broad sense (>75%) were found for 100 seed weight, seed yield per plant, days to 50 per cent flowering, biological yield per plant, plant height, harvest index and secondary branches per plant in both the environments. High genetic advance in per cent of mean (>20%) were recorded for seed yield per plant, 100 seed weight, secondary branches per plant, biological yield per plant, pods per plant and harvest index in both the environments. High heritability coupled with high genetic advance in per cent of mean were found for 100 seed weight, biological yield per plant, seed yield per plant, harvest index, secondary branches per plant and pods per plant in E1 and E2..
