Present experiment comprised four diverse parents viz., KM-22-24, GM-6, HUM-27 and GM-8 and their F2 populations of the crosses viz., cross-I (KM-22-24 X GM-6) and cross-II (HUM-27 X GM-8) to elucidate information on variation, correlation as well as direct and indirect effects of different characters contributing towards seed yield of segregating populations of green gram. The experiment was carried out in summer-2023 (crossing), kharif-2023 (selfing) and summer-2024 (evaluation) at the Pulses and Castor Research Station, Navsari Agricultural University, Navsari. The segregating populations manifested increased mean values over the parental means in the cross-I (KM-22-24 X GM-6) for days to maturity, plant height, branches per plant and pod length, while in cross-II (HUM-27 X GM-8), for the traits viz., branches per plant and pods per plant. The phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) exhibited wide variation for most of the characters in all the segregating populations of both the crosses. In cross-I, the traits viz., branches per plant, seeds per pod and seed yield per plant showed moderate value of GCV and higher value of PCV while in the cross-II, the traits like branches per plant and seeds per pod showed higher value of GCV and PCV. This higher value indicated the greater scope of improving these characters by applying the selection in an appropriate direction. Higher heritability coupled with high genetic advance as per cent mean was observed for days to flowering and plant height in both the crosses. While in cross-I, days to flowering, days to maturity, plant height and pod length showed high heritability coupled with high genetic advance per cent mean. Similarly, in cross-II days to flowering, plant height, branches per plant, seeds per pod and seed yield per plant showed the same results. Hence, priority should
be given to these traits in formulating selection strategies to obtain desirable genetic gain by selection.
