A study on variability, heritability and genetic advance in 13 genotypes of soybean were carried out for yield and yield component traits. Observations on 11 characters were recorded. Analysis of variance revealed highly significant differences among the genotypes for the all the characters. The range was maximum for plant height (39.27-77.73) followed by number of pods per plant (35.87-61.40). The genotypic coefficient of variation and phenotypic coefficient of variation were high for pod weight per plant (g) followed by seed yield per plant (g) indicate the presence of wider adaptability for these traits in the genotypes studied, suggested the less influence of environment in the expression of characters. High heritability coupled with high genetic advance as percent of mean was observed for days to 50% flowering, plant height (cm), number of pods per plant, number of seeds per pod, pod weight per plant,100 seed weight, biomass and seed yield per plant indicating additive gene action and the ample scope for improvement in these traits through simple selection.

Keywords: Genetic variability, heritability, soybean and Genetic advance
