The productivity of sesame in Ethiopia is below the world avergae mainly lack of high yielding improved variety. Understanding of association and chief contributors of characters becomes essential. Therefore, this study was conducted to assess the association and pricinpal characters among yield and 19 yield components. Hundered sesame genotypes were evaluated in 10x10 triple lattice design at Werer from 2017 to 2018. The combined analysis of variance revealed that genotypes differed significantly. Seed yield showed positive and significant correlation with length of capsule bearing zone, length of first capsule, capsule length, capsule per main axis, number of capsule per plan, harvest index and oil content. Path coefficient analysis revealed capsule per main axis, capsule per plant and harvest index had positive direct effect on yield. Principal component analysis showed that seven principal components have accounted 78.67% of the total variation. The present study showed that to increase sesame seed yield, the genotypes should possess more number of capsules per main axis, capsule per plant and high harvest index.This study suggested these characters are important yield contributing traits and selection based on these characters would be most effective in line with molecular markers assisted breeding should be considered in the future.
Key Words: Oil crop, Sesame, Character, Correlation, Path coefficient and Principal Component.
