Description
The present study comprised of 154 RILs developed from four different crosses in Indian bean. This RIL population was evaluated in augmented design along with five different checks during kharif-rabi 2021-22 to study variability parameters. Analysis of variance unveiled significant genotypic mean square values for all six traits in present study indicating presence of sufficient variability in RIL population. High estimates of GCV and PCV were observed for plant height, racemes per plant, pods per plant and seeds per pod. Less difference between GCV and PCV values for these traits indicated less environmental influence. Moreover, higher magnitude of broad sense heritability coupled with higher genetic advance was observed for all the traits except seeds per pod indicated involvement of additive gene effects and less impact of environment. Thus, there is ample scope for improvement of these traits through simple selection.
