In this study the genetic variability of soybean lines generated from segregating populations introduced from USA was evaluated. A total of 97 soybean genotypes that were introduced from USA along with three checks were grown in 10×10 simple lattice design with two replications at Jimma, Ethiopia. The ANOVA results showed significant (p≤0.05) variations in days to flowering, days to maturity, plant height, number of branches per plant, number of pods per plant, pod length, number of seeds per pod, number of seeds per plant, 100 seed weight, above ground biomass, harvest index, and grain yield indicating a considerable variability among the tested genotypes for the characters. Characters viz., plant height, number of branches per plant, above ground biomass and grain yield had high heritability and high genetic advance. Grain yield had positive and high significant (p≤0.01) genotypic correlations with harvest index (0.746) and 100 seed weight (0.267). Similarly, grain yield showed positive and significant (p≤0.05) genotypic associations with number of seeds per plant (0.225) and above ground biomass (0.205). This implies that higher mean values for these traits tend to improve grain yield in soybean. Cluster analysis grouped the genotypes into three clusters with the maximum squared distance found between cluster II and III. The principal component analysis revealed that the first four principal components (PCs) accounted for more than 71.25% of the total variation. The variability amongst the tested genotypes, heritability and genetic advance, as well as the associations in the tested traits provide information for an increased soybean productivity using this lines.
