Abstract: Thirty one genotypes of Dolichos bean (Lablab purpureus) were evaluated to study the genetic variability on yield, yield contributing and related characters via days to first flowering, days to 50% flowering, length of inflorescence, number of flowers per inflorescence, number of pods per inflorescence, days to first pod harvest, pod length, pod width, number of grains per pod, mean pod weight, pod yield per plant and pod yield per hectare. The genotypic and phenotypic coefficient of variation, heritability and genetic advance were calculated. These genotypes showed considerable amount of variability for all the characters studied. The highest and lowest coefficient of variation was observed for pod yield per hectare and days to first pod harvest respectively. Little or no difference between the phenotypic and genotypic coefficients of variability in the expression of various horticultural traits studied indicated that these were less influenced by environment. All these traits except days to first pod harvest, pod width and number of grains per pod exhibited higher heritability coupled with high genetic advance which suggests the role of additive gene action in the expression of these characters and could be improved through selection. The genotypes used in the study are of diverse nature and can be used in the breeding programme for development of superior genotypes in Dolichos bean.
