Sorghum is one of the major staple food crops in eastern Ethiopia where the area is known for an uncertainty of rainfall. Therefore, this study assessed the direct and indirect effects of yield-related traits on sorghum grain yield and estimated associations among yield and yield-related traits of sorghum genotypes. Thirty-four sorghum genotypes and two improved varieties in 6x6 simple lattice designs at Fedis Agricultural Research Center in the 2019/20 cropping season. The result of correlation analysis suggested that the magnitude of genotypic correlation coefficients was higher than the corresponding phenotypic correlation coefficients for most of the suggesting that were inherent relation with other traits. Grain yield showed significant and positive phenotypic correlation with above-ground biomass(r=0.240*), harvest index(r=0.652**), number of seeds per panicle(r=0.408**), and panicle weight(r=0.390**). The strongest phenotypic associations were observed between days of flowering and maturing (r=0.930**) followed by Leaf area(r=0.379**) and Plant height(r=0.359**). In addition, path coefficient analysis provides a means of finding both direct and indirect effects of traits.
