Abstract: The present investigation carried out by Line X Tester analysis on sesame (sesamum indicum L.) over environments at the Agricultural Research Station, J.A.U., Amreli and Department of Seed Science and Technology, College of Agriculture, Sagadividi Farm, J.A.U., Junagadh, Gujarat. These 40 crosses along with a two checks, G.Til-2 and G.Til-3 were evaluated in a four environments were created through different time and location for sowing during summer 2016. Heterobeltiosis crosses for high seed yield per plant and its components in the crosses viz., AT-319 x G.Til-10, AT-341 x G.Til-10, AT-322 x G.Til-10, AT-306 x G.Til-10 and AT-253 x G.Til-10 exhibited significant and positive heterobeltiosis for high seed yield per plant. The crosses AT-319 x G.Til-10 and AT-341 x G.Til-10 manifested significant and desirable heterobeltiosis and standard heterosis for seed yield per plant. These also recorded significant and positive heterosis for number of branch per plant, number of capsules per plant and number of seeds per capsule. Heterotic effects for seed yield per plant could be a result of combinational heterosis. Hence, to obtain maximum heterotic effects for seed yield per plant, desired level of heterosis for each component character should be worked-out to identify superior hybrids.
