An investigation was carried out to assess the genetic variability of seven quantitative characters in F2 population, to study the association and path coefficient analysis of yield and its attributing traits. High phenotypic coefficient of variation and genotypic coefficient of variation estimates were recorded for number of pods per plant, seed yield per plant, number of pods per branch, number of branches per plant and 100-seed weight in the F2 segregating population of the cross L 550 × PG 06102 which indicates greater scope for selection to improve upon these characters. High heritability coupled with high genetic advance as per cent of mean (GAM) was observed for number of pods per plant, seed yield per plant, number of pods per branch, plant height, 100-seed weight and number of branches per plant indicating that these traits are under the control of additive gene action. Correlation studies for seed yield and its attributing traits revealed significant positive correlation of plant height, number of branches per plant, pods per plant, pods per branch and 100-seed weight with seed yield per plant inferring that these traits strongly influenced seed yield per plant. Path coefficient analysis revealed that number of pods per plant exhibited direct effect on seed yield per plant followed by number of pods per branch, number of branches per plant, 100-seed weight and plant height indicating the importance of these characters in selection programme for increasing the seed yield.
