In this paper, correlation and path coefficient analysis for finding all possible relationships between grain yield and plant growth components have been carried out. The plant growth components are not only individually correlated with yield, but also correlated among themselves. The inter-character correlations among grain yield (GY), number of grain per plant (NG), number of pods per plant (NP), leaf area index (LAI), plant height (PH), weight of grain per plant (WG), number of branches per plant and biological yield (BY) were measured for this study. The correlation analysis reveals that the number of pods per plant (0.649**), the number of grains per plant (0.592**) and the number of branches per plant (0.798**) are significantly correlated with grain yield. Among the causal characters, the number of branches per plant exhibits the highest direct positive effect (0.797) with grain yield. Finally, it is concluded that the number of grain per plant, number of branches per plant and number of pods per plant should be considered as indices for selecting high yielding soybean variety.
