Abstract: Fifty six sesame genotypes comprising forty hybrids and fourteen parents genotypes along with a two checks, G.Til-2 and G.Til-3 were evaluated for physiological stability parameters for plant height, biological yield per plant, harvest index, leaf area at 60 days, chlorophyll content at 60 days with seed yield per plant. The stability analysis indicated the presence of G x E interaction were found significant for all the characters when tested against pooled error. The mean squares due to E + (G x E) were significant when tested against the pooled error for all the characters. Here, hybrid AT-319 x AT-285 had below average stability which well adapted to favourable environments for harvest index and seed yield per plant. The parents, Khadkala-S for biological yield per plant, IS-209 for harvest index, AT-341 for chlorophyll content at 60 days and G.Til-3 & AT-322 for seed yield per plant were found average stable for environments. Bhuva-2 x G.Til-10 ( =6.49) for seed yield per plant and IS-209 x G-Til10 & AT-306 x RT-54 for plant height had greater tolerance to environmental changes and thereby this hybrids would have specific adaptability to poor yielding environments. Therefore, these genotypes can be recommended for varied environments to exploit their high yield potential with physiological parameter traits.
