The present investigation on sesame comprised of a half-diallel set of seven parents and their 21 crosses. The experiment was laid out in randomized block design with three replications at College Farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari during late kharif 2016-17. The observations were recorded on days to flowering and days to maturity, plant height (cm), number of branches per plant, number of capsules per plant, capsule length (cm), seed yield per plant (g), 1000 seed weight (g), harvest index (%) and oil content (%) on randomly selected five competitive individual plants. The data were subjected to estimation of heterosis. Analysis of variance revealed significant differences among the genotypes, hybrids and parents for all the traits except harvest index for parent studied. Several crosses exhibited significantly desirable heterobeltiosis and economic heterosis for seed yield per plant and other characters. On the basis of per se performance and estimates of heterobeltiosis, the crosses AT 242 x AT 255 (17.58%) and AT 242 x G.Til 3 (17.19%) were found to be most promising for seed yield per plant, hence could be evaluated further to exploit the heterosis or utilized in future breeding programme to obtain desirable segregants for the development of superior genotypes.
