Abstract:
The investigation on "Genetic variability, character association and divergence studies in bush type of dolichos bean (Lablab purpureus L.) germplasm". The analysis of variance proved highly significant (P=0.01 and P=0.05) differences among the genotypes for all the traits studied indicating the higher magnitude of variation in the germplasm. The range, mean, phenotypic variance, genotypic variance, phenotypic coefficient of variation, genotypic coefficient of variation, broad-sense heritability, genetic advance and genetic advance as per cent over mean were calculated. The genotypes showed considerable amount of variability for all the traits. The high estimates of heritability coupled with high genetic advance as per cent over mean were noticed for the traits viz., plant height, days to first flowering, days to first picking, number of green pods per cluster, number of clusters per plant, number of green pods per plant, green pod length, average pod weight, green pod yield per plant, green pod yield per plot, protein, shelling per cent, crude fiber, number of seeds per pod and seedling length which indicates dominance of additive components for these traits and hence direct selection would be more effective in improving these traits.
