Due to hereditary causes of correlations through pleiotropic action or developmental interactions of genes, associations of traits are crucial in breeding and genetic studies. These associations also yield trustworthy information about the type, degree, and directions of selection. The experiment was conducted in 8 x 8 simple lattice design during the 2021 main cropping season at Assosa Agricultural Research Center, western Ethiopia to determine the interrelationship among the traits and know the direct and indirect effects on the yield of 64 sesame genotypes based on 15 quantitative traits. For the majority of the traits under study, the results indicated a large variation in genotypes. This suggests that there is enough variation among various genotypes for the majority of the significant traits. Except for internode length and capsule length, the correlation result showed that seed yield had highly significant positive correlations with 12 quantitative traits and negative correlations with the bacterial blight disease severity. The number of capsules per plant, days to maturity, and seeds per plant all revealed a strong direct impact on seed yield. These traits also had indirect or direct effects on oil content, so increasing seed yield also increased oil content through those traits.
