ABSTRACT: Fifteen genetically diverse genotypes were evaluated at Phanda, Dhar and Silwani in two consequent years to know the real heritable genetic variation for seed yield and its components characters in Soybean. In estimates of heritable genetic variability recorded in pooled analysis over environment were lower in magnitude than their corresponding estimates in individual environment. In pooled analysis plant height, 100-seed weight, pod per plant, seeds per pod and branches per plants exhibited moderate to high estimates of variability. Heritability with moderate to high estimates of genetic advance as percentage of mean. Seed yield per plant, biological yield per plant, harvest index and seeds per pod should low to moderate estimate of heritable genetic variation.
