Abstract
An '8x4' line x tester analysis in sesame was conducted to study 8 important economic traits of sesame, namely days to 50% flowering, plant height, number of primary branches per plant, capsule length, number of capsules per plant, 1000-seed weight, oil percentage and single plant yield. Association analysis revealed that seed yield per plant was positively and significantly correlated with plant height, number of primary branches per plant, capsule length, number of capsules per plant and 1000-seed weight. Partitioning of total correlation coefficient into components of direct and indirect effects revealed that the number of capsules per plant was the only character which contributed to seed yield directly. The other traits contributed indirectly through number of capsules per plant. It is suggested that the number of capsules per plant can be taken as an index for improving seed yield in sesame.
