Abstract:
The field experiment was conducted to study genetic variability in pole type of dolichos bean genotypes(Lablab purpureus L.). Analysis of variance revealed highly significant differences among the genotypes for most of the characters under the study. The range, genotypic and phenotypic coefficient of variation, heritability, genetic advance and genetic advance as per cent of mean were calculated. The genotypes showed considerable amount of variability for all the traits. High estimate of heritability coupled with high genetic advance over per cent of mean were noticed for days to first flowering, number of flowers per cluster, number of pods per cluster, number of pods per plant, average pod weight and pod length which indicates that these attributes are under the influence of additive gene action. Thus, there was plentiful scope for improving these characters through direct selection.
