Abstract
An experiment was conducted to study genetic variability, heritability, and genetic advance among 25 soybean genotypes. Analysis of variance revealed significant differences for all the thirteen tarits. For most of the features, the discrepancies between phenotypic and genotypic coefficients of variation (PCV and GCV) were small, indicating little environmental influence on their expression. For the number of pods/plant and the number of seeds/plant, high heritability and genetic advance with a high GCV were determined to be advantageous features for soybean improvement by phenotypic selection, with a high predicted genetic gain. The traits with higher heritability and GA value may indicate their variability and high selective value. Genetic variation is crucial to the effectiveness of yield improvement efforts since it is a major component in broadening gene pools in any particular crop population. As a result, the study's goals were to evaluate genetic variability.
