An experiment was conducted to study the expression of heterosis for ten characters in forty five crosses of sesame developed by crossing five lines with nine testers in line x tester mating design. The analysis of variance (line x tester) revealed significant differences among the genotypes for all the characters studied except for number of secondary branches. Heterosis was worked out over midparent, better parent and standard parents viz., CO 1 and TMV 7. The cross TMV 5 x ORM 7 expressed significant and positive heterosis over mid parent, better parent and two standard varieties for single plant yield along with high per se performance. The crosses, TMV 5 x ORM 7, TMV 6 x VRI 1 and TMV 3 x CO 1 expressed highly significant standard heterosis for most of the traits including single plant yield and hence could be exploited for development of high yielding varieties.
