Higher GCV and PCV coupled with narrow difference between PCV and GCV were found for pod yield per plant, kernel yield per plant, pods per plant, Specific Leaf Area, SCMR, plant height and days to first flowering in all the three crosses indicating individual plant selection can be followed for improvement of these characters. High heritability coupled with high genetic advancement as a per cent of mean was observed for pod yield per plant, kernel yield per plant, pods per plant, SCMR and SLA indicating the involvement of additive gene action for expression of these traits in crosses studied. Pods per plant, kernels per plant, kernel yield per plant, SCMR exhibited high positive effect on development of pod yield per plant in all the generations studied suggesting pod yield per plant could be increased upon improving of these pod yield contributing characters. Presence of significant positive correlation between F5 to F6 generation for pods per plant, pod yield per plant, kernel yield per plant, kernels per plant, SCMR and SLA implies that these traits can be used as selection criteria from F5 generation onwards. High broad sense coupled with high narrow sense heritability was observed for pods per plant, pod yield per plant, kernel yield per plant, SCMR and SLA in F6 generation suggesting the alleles which are involved in expression of these traits are fixed. The segregants which were selected having higher SCMR, lower SLA and higher pod yield per plant.ennullThesis
