Fifty Clusterbean genotypes were evaluated to estimate variability parameters, association between seed yield and its attributes along with direct indirect effect during kharif 2019 at SDAU, Sardarkrushinagar, Gujarat. The high GCV, PCV as well as high heritability coupled with high genetic advance were recorded for number of fruiting branch per plant, number of cluster on main stem, number of cluster per plant, number of pod on main stem and number of pod per plant indicated additive gene effects. Seed yield exhibited highly significant and positive correlation with plant height, number of cluster per plant, number of pod per plant and 100 seed weight while, non-significant and negative association with days to 50 per cent flowering, pod length, endosperm percentage and protein content. Seed yield possessed high and positive direct effects via. days to 50 per cent flowering, number of cluster per plant, number of pod per plant, number of seed per pod, 100 seed weight and endosperm percentage. Thus, more weightage is given to those genotypes which possess early flowering, more number of cluster on main stem, number of cluster and number of pod per plant and high 100 seed weight for improve the efficiency of selection.
