Abstract: The present investigation was conducted with the F3 breeding lines derived from three crosses viz., DGGV-7 × V-02-709, DGGV-7 × V-02-802, DGGV-2 × SML-1815 along with their parents used as checks. The progeny lines were evaluated for estimation of genotypic coefficient of variation (GCV), phenotypic coefficient of variation (PCV), heritability and genetic advance. The correlation study was undertaken among the ten selected quantitative characters. The analysis of variance showed, the progeny lines derived from the cross DGGV-7 × V-02-709, recoded very high significant variation for the characters like the number of branches per plant (2.988), pod length (2.363) and seed yield per plant (13.007g). The 100 seed weight (4.7g) was observed in the cross derivative of DGGV-2 × SML-1815 with high heritability 73.26 per cent and moderate genetic advance under mean (19.65). The breeding lines of DGGV-7 × V-02-709 have recorded mean seed yield 3.7 g with the range of 3.22 to 4.65 g and the PCV (17.35%), GCV (14.23%) was moderate with high heritability (72.12%) coupled with moderate genetic advance over mean (17.45%). There is a positive significant correlation was observed between plant height, number of clusters per plant, number of pods per plant, number of seeds per pod and seed yield per plant. Therefore, these characters should give higher priority at the time of selection for improvement of yield in greengram.
