An investigation was conducted on studies on genetic variability for yield and yield attributing characters in dolichos bean (Dolichos lablab 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 heritability coupled with high genetic advance as per cent of mean was recorded for plant height at harvest, number of leaves per plant at harvest, days to first flowering, days to 50 per cent flowering, number of flowers per cluster, pod length, pod width and pod thickness, number of pods per cluster, number of pods per plant, average pod weight, average green seed weight, pod yield per plant, pod yield per plot, pod yield per hectare and shelling per cent, which illustrates that these characters are under the influence of additive gene action. Thus, there is a bountiful scope for improving these attributes through direct selection.
