ABSTRACT

The experiment was conducted during Kharif, 2014 to estimate genetic variability and genetic parameters in 48 diverse genotypes of clusterbean for 16 quantitative characters. The analysis of variance revealed significant differences among all 48 genotypes for all the characters studied. The highest estimates of coefficients of variation were registered for number of branches per plant followed by number of clusters per plant, number of pods per cluster and seed yield per plant. High heritability coupled with high genetic advance was observed for number of branches per plant and number of clusters per plant indicating the presence of additive gene action in the expression of these characters. High estimates of genotypic coefficient of variation, heritability and genetic advance recorded for number of branches per plant and number of clusters per plant indicated that variation in these traits is high and these traits appear to be governed by additive gene action. Hence, simple directional selection may be effective to improve these traits.
