Sesame (Sesamum indicum L.) is one the most important oil seed crop in India as well as world. Based on growth of human population the needfulness of the Sesame oil is high compare to other oil seed crops. The present situation productivity of sesame was low due to reduction of cultivable land and low numbers of high yield varieties. In this present paper deals to produce high yield Sesame varieties by using intraspecific hybridization with conventional breeding techniques. Five varieties of Sesame (TMV-3, TMV-4, TMV-7, VRI-1 and VRI-2) were selected and made 20 intervarietal crosses.(both direct and reciprocal) The crossed P1 seeds were used to raise as F1 population in the field. The growth performances and productivity were observed and its seeds were stored carefully. The F1 seeds were used to raise for F2 population to identify the heterosis of Sesame and analyse the hybrids from the intervarietal crosses. In the present study to deals with the following parameters such as Plant height, Number of branches per ssplant, Number of leaves per plant, Stem diameter, Number of capsule per plant, Seed yield per plant and Oil content were analyzed to identify the best cross combination and hybrid from both direct and reciprocal crosses.
