Abstract
Genotypic correlations and path coefficients were analysed in 10 genotypes of soybean [(Gylcine max (L.) Merr ] of diverse genotypic origin for six quantitative traits. Grain yield showed positive and significant genotypic correlation with plant height, 100-seed weight and pod height. Path coefficient analysis indicated that plant height had a very high positive direct path followed by 100-seed weight. Although the genotypic association of pod height was positive and highly significant, it had direct negative path towards grain yield. Pods/plant, pod height and days to maturity (DM) had negative association as well as direct negative path towards yield. For reliable selection index, plant height and 100-seed weight were the characters of prime importance followed by pod height.
