ABSTRACT
Estimation of variability, heritability, genetic advance, correlation and path analysis were carried out for fifteen characters in seventy diverse genotypes of soybean. Analysis of variance revealed that mean squares due to genotype were found significant for all the traits under study except oil content, indicated that enormous phenotypic variability was present among the genetic materials studied. The highest genotypic and phenotypic coefficient of variances were observed for pods per plant, primary branches per plant and clusters per plant and it was lowest for oil content and days to maturity. High heritability, genetic advance and genetic advance as per cent mean were observed for pods per plant as well as plant height. Seed yield per plant was positively and significantly correlated with clusters per plant, biological yield per plant, pods per plant and harvest index. Biological yield per plant recorded highest positive direct effect on seed yield per plant followed by harvest index, days to flowering. The studies suggest that for improvement in high yielding genotypes of soybean make selection for biological yield per plant, pods per plant, primary branches per plant and clusters per plant.
