The objective of this study was to estimate the genetic variability and heritability for grain yield and quality traits in soybean as selection criteria in breeding for higher grain yield. The experimental material for the study comprised of twenty soybean genotypes. The analysis of variance revealed significant variations among the genotypes. Estimates of phenotypic (PCV) and genotypic (GCV) coefficients of variation indicated that the values of PCV were higher than that of GCV. This portrayed the influence of environmental factors in the variation exhibited. High values of PCV and GCV were observed for number of pods, plant height, number of leaves and seed yield indicating presence of sufficient genetic variability for selection in these traits. High heritability coupled with high genetic advance observed for plant height and number of pods per plant suggests that selection could be effective for these traits.
