Abstract:
Genetic variability & trait association analysis were studied for yield and its attributing traits in thirty diverse clusterbean genotypes under rainfed conditions. The analysis of variance revealed, highly significance difference among the genotypes for all the studied traits. Traits viz., days to flowering, number of pod per plant and seed yield per plant exerted high GCV and PCV values, respectively. High heritability with high genetic advance as per cent of mean recorded in six traits viz., days to flowering, days to maturity, number of branch per plant, number of pod per plant, gum content and seed yield per plant, respectively. Under rainfed conditions number of pod per plant, number of seed per pod and test weight were significantly positively correlated with seed yield per plant. Number of pod per plant showed highest positive direct effect towards the seed yield per plant followed by days to flowering and number of seed per pod. Based on mean performance, genotypes GG 1907, GG 2108, GG 2109, GG 2111 and GG 2114 were superior for all the characters under study along with yield. For indirect selection in yield, pod per plant and number of seed per pod can be considered for future breeding strategies.
