Abstract: The present investigation was carried out at N. E. Borlaug Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand, India, during kharif, 2016 and 2017 with 298 genotypes (294 entries and 4 checks) of soybean for eleven qualitative and twelve quantitative characters to assess genetic divergence, genetic variability, inter-character correlation and their direct and indirect effects and molecular genetic diversity. In general, the magnitudes of PCV were higher than those of GCV and ECV for all the characters with a close correspondence between the values of PCV and GCV for majority of the characters under study. This indicated a minimum role of environment in their expression and hence, selection based on phenotype could be rewarding for such characters. Highest values of PCV, GCV and Genetic advance as% of mean was observed for plant population / plot followed by dry matter weight and seed yield per plant, respectively. High estimates of heritability and genetic advance were reported for plant population per plot, dry matter weight per plant, plant height, number of nodes per plant, number of pods per plant, 100-seed weight, harvest index, seed yield efficiency and seed yield per plant which indicated a role of additive gene effects in their expression.
