SUMMARY
The present investigation was conducted at Dry Land Research Area, CCS Haryana Agricultural University, Hisar during kharif, 2022. Data were recorded on 17 quantitative traits for genetic variability and association studies among morpho-biochemical traits using 50 cluster bean genotypes. High PCV, GCV, heritability along with high genetic advance as percent of mean were observed in no. of pods per plant, no. of clusters on main stem, no. of clusters on side branches, no. of clusters per plant and no. of branches per plant. Seed yield per plant was positively and significantly associated with no. of pods per plant, no. of clusters on side branches, no. of clusters per plant, no. of pods per cluster on main stem, no. of pods per cluster on side branches, 100 seed weight and gum content. Path analysis revealed that the no. of pods per plant, 100-seed weight, no. of branches per plant, no. of pods per cluster on main stem, days to maturity, days to 50% flowering and gum content would be selected as important ones towards seed yield as they showed high positive direct effect on seed yield.
Key words: Cluster bean, variability, correlation and path coefficient
