Genetic variability studies in cluster bean [Cyamopsis tetragonoloba (L.) Taub.] for growth, yield and quality parameters

Abstract

The study on genetic parameters of 74 cluster bean genotypes collected from different parts of the country revealed, high estimates of variation for number of branches (90 DAS), number of clusters per plant, number of pods per cluster, pod length, pod weight, vegetable pod yield per plant, pod yield per plot, pod yield per hectare, dry pod yield per plant, weight of ten dry pods, seed yield per plant, seed yield per plot and gum content of seed endosperm The high estimates of heritability coupled with high values of genetic advance over mean (GAM) were noticed for traits like, plant height (cm) (90 DAS), number of branches (90 DAS), number of clusters per plant, pod length, pod weight, pubescence, seed yield per plant, seed yield per plot and seed gum content. These outcomes showed prevalence of additive constituents for these characters and hence for improving these traits by direct selection method would be more effective.
