Soybean [Glycine max (L.) Merrill] is highly nutritious with neutraceutical valued legume crop grows across the world. Information on different genetic estimates is used to select desirable traits and genotypes for crossing programme. The present investigation was undertaken to estimate different genetic parameters i.e. genetic variability, heritability, character association and principal component on thirty four advanced breeding lines of soybean along with two checks sown in Randomized block Design during Kharif, 2018 at JNKVV, Jabalpur. The highest PCV and GCV (41.16 and 40.43 %) were recorded for number of seeds per pod. Genetic advance as percentage of mean was high (>75%) for number of seeds per plant and number of seeds per pod. The number of pods per plant was highly significantly correlated with number of seeds per plant (0.79**). Path coefficient analysis was also revealed that substantial higher positive direct effect of number of seeds per plant and number of seeds per pod on seed yield. Out of five principle components, PC1 had the highest variance percentage with Eigen value of 2.17. Number of seeds per plant contributed highest (64 %) in PC1. Hence, all these traits could be utilized in soybean crossing programme for further yield improvement.
