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

An experiment was carried out to study the direct and indirect effects on the pod and seed yield in cluster bean using 15 accessions. The path coefficient analysis which splits total correlated coefficient of different characters into direct and indirect effects on pod and seed yield per plant in such a manner that the sum of direct and indirect effects is equal to total genotypic correlated. The significant difference among the genotypes for all the characters under study suggested that there was ample scope for selection of promising cluster bean genotypes for vegetable yield and seed yield improvement. Pods/plant had positive direct effect on pod yield/plant. It exhibited positive indirect effect through days to 1st flowering, days to 50% flowering, plant height 45 days, plant height 90 days, days to 1st pod picking, ten fresh pod weight, pod length and pod yield/plant. Fruit clusters/plant had direct negative effect on seed yield/plant. It exhibited positive indirect effect through seeds/pod and 100 seed weight. Seeds/pod had direct negative effect on seed yield/plant. It exhibited positive indirect effect through fruit clusters/plant and pods/cluster.
