Abstract

Twenty one diverse winged bean genotypes were evaluated for phenotypic and genotypic variability, heritability and genetic advance in nine quantitative traits. Considerable amount of genetic variability was exhibited by days to 50% flowering, pod length, dry pod weight, 100 seed weight and grain yield per plant. Days to 50% flowering, days to maturity, number of pod per plant, 100 seed weight and grain yield per plant gave high heritability estimates with moderate genetic advance, which indicates additive gene effects to provide a rapid genetic improvement. The genetic advance and heritability estimates suggested that the characters e.g. days to 50% flowering, days to maturity, number of pod per plant, dry pod weight, 100 seed weight and grain yield per plant were under additive gene effects.
