The present investigation Ph.D thesis entitled “Genetics architecture of seed yield and its components in sesame (sesamum indicum L.) over environments” was conducted 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 56 genotypes 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. The stability analysis indicated the presence of G x E interaction were found significant for all the characters when tested against pooled error excepts days to flowering, days to maturity, width of capsule and number of capsule per leaf axil. The mean squares due to E + (G x E) were significant when tested against the pooled error for all the characters. In this direction, two hybrids AT-322 x G.Til-10 and AT-319 x AT-285 had below average stability which well adapted to favourable environments. The parents, AT-319 for length of capsule, G.Til-3 for width of capsule, AT-319 for number of capsule per plant, IS-209 for number of seed per capsule, G.Til-1 for 1000 seed weight and G.Til-3 for seed yield per plant were found average stable for environments.. Check. Bhuva-2 x G.Til-10 ( =6.49) had greater tolerance to environmental changes and thereby this hybrids would had specific adaptability to poor yielding environments. Hence, these parents may be used in the breeding programmes aimed at improving seed yield and yield components, in addition to incorporation of phenotypic stability for the traits in sesame.
