Abstract: Forty diverse clusterbean genotypes were analyzed for genetic variability, heritability and genetic advance for yield and its contributing characters. The genotypes were significantly different for all the characters. High heritability along with high genetic advance (GA) as per cent of mean was recorded for number of branches/plant, biological yield/plant, seed yield/plant, number of clusters/plant and number of pods/plant indicating that these were controlled by additive gene effects and selection would be rewarding for these characters. The PCV estimates were invariably higher than their corresponding GCV values thereby suggesting the role of environmental influence. High estimates of GCV and PCV were observed for number of branches/plant, biological yield/plant, seed yield/plant, number of clusters/plant and number of pods/plant suggesting that selection based on these characters would facilitate successful isolation of desirable genotypes. The genotypes RGC 986, RARI-CB-18-25, HG 2-20, RGC 1017 and RARI-CB-18-20 were found promising having high mean performance for seed yield and other related traits.
