The present investigation on study of correlation and path analysis was carried out in soybean cv, PK 1092 treated with three doses of gamma rays (20 kR 30 kR and 40 kR) and three concentrations of Ethyl methane sulphonate (EMS) (0.05%, 0.10% and 0.15%) and their combinations in M2 generation for twelve quantitative characters. The seed yield per plant had strong positive association with number of pods per plant, number of seeds per pod, total day matters weight (g) per plant, harvest index, seed yield efficiency, oil content and protein content at both genotypic and phenotypic level. The characters days to 50% flowering, day to maturity, number of pods per plant, number of seeds per pod, total days matter weight (g/plant), harvest index, 100 seed weight, oil content and protein content had positive direct effect on seed yield per plant at genotypic level. The selection based on number of pods per plant, number of seed per pod, total day matter per plant, harvest index, seed yield efficiency and 100 seed weight could help in genetic improvement of seed yield per plant in soybean population under study.
