An experiment was conducted on soybean at All India Coordinated Research Project on Soybean, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani with view to study correlation and path analysis effects for yield, yield components , oil and root nodulation traits in 40 genotypes of soybean. Correlation studies indicated the importance of days to maturity, plant height, 50% flowering, 100 grain weight, number of pods per plant, number of nodules/plant, nodule dry weight and root length. The path coefficient of analysis revealed maximum contribution of days to maturity, days to 50% flowering, oil content, number of nodules per plant, plant height, 100 grain weight and root length. The characters days to maturity, days to 50 % flowering, 100 grain weight, number of nodules per plant and root length had strong association with yield. It also showed the highest direct effect and indirect effect through other component traits. This indicated that direct selection for these characters will help to enhance the breeding efficiency for grain yield in soybean.
