Present investigation of geneticvariability, correlation, path and genetic divergence analysis for yield and yield contributing characters in 30genotypes of soybean was carried out during kharif, 2019 at JNKVV, College of agriculture (Ganj Basoda, M.P.). The genotypes MAUS-71, SL-525 and JS 71-05 found highest yielding among all the 30 genotypes. Highest estimates of PCV were observed for primary branching per plant, secondary branching per plant, grain yield per plant, harvest index and seed yield per plot, and higher GCV were observed for primary branches per plant, secondary branches per plant, grain yield per plant, harvest index and seed yield per plot. High estimates of heritability was recorded for primary branches per plant, plant height, secondary branches per plant, number of pod plant, day to 1stpod initiation and grain yield per plant and high genetic advance was recorded for primary branches per plant, secondary branches per plant, grain yield per plant. The correlation analysis revealed that grain yield per plant had significant positive association with harvest index, number of seed per pod, secondary branching per plant and primary branching per plant. Path coefficient analysis at phenotypic level revealed that number of seed per pod was observed the maximum positive direct effect on grain yield per plant followed by number of pod per plant, secondary branches per plant, 1st pod initiation, days to 50% flowering and number of seeds per plant.
