Abstract: Six generations (P1, P2, F1, F2, BC1 and BC2) derived from three crosses (BDN 708 X BSMR 571, BDN 708 X BDN 2010-1 and BDN 711 X SKNP 0632) between different parents (BDN 708, BSMR 571, BDN 2010-1, BDN 711 and SKNP 0632) along with check BDN 716. The material was evaluated during Kharif 2018 in randomized block design with randomization of generation replicated twice at Agricultural research station, Badnapur. Narrow sense heritability was higher due to higher value of additive gene action for all the crosses. High estimates of heritability were observed in the cross BDN 708 X BSMR 571 for days to 50% flowering, days to maturity, number of primary branches per plant, pod length and seed yield per plant. The cross BDN 708 X BDN 2010-1 showed high heritability for plant height, number of seeds per pod and pod length. The cross BDN 711 X SKNP 0632 showed high heritability for number of primary branches per plant, number of pods per plant and pod length. Some crosses showed negligible heritability. Narrow sense heritability play an important role for selection of traits in plant breeding for crop improvement.
