Correlation coefficient and Path coefficient analysis for seed yield and its component traits in cluster bean [Cyamopsis tetragonoloba (L.) Taub.] Genotypes

Abstract

The present study was carried out on thirty genotypes of Cluster bean [Cyamopsis tetragonoloba (L.) Taub.] Genotypes with view to find out the correlation and path co-efficient values among the grain yield components. The seed yield per plant had positive correlation with biological yield (0.8056), Harvest Index (0.8715), Cluster per plant (0.7694) and test weight (0.7322) while negative correlated with days to 50% flowering(-0.1862) and Days to maturity (-0.3490) at genotypic level. Seed yield had significant negative correlated with Days to maturity (-0.2808) at phenotypic level.
