Study of genotype x environment interaction of ten parents along with their 45 F₁ progenies were evaluated in a randomized block design with three replications during summer kharif 2020-2021 under three different environmental conditions viz., normal, late and extreme late sowing for yield and its attributes. The stability analysis for yield and yield attributes was carried out as per model of Eberhart and Russell for knowing causes of stability. Genotype x environment interaction was significant for all the traits under study. On basis of stability analysis, parents TKG-22, GT-10 and RT-351 and crosses TKG-22 x GT-10, RT-372 x RT-103, TC-25 x RT-46, TC-25 x RT-46, RT-103 x GT-10 exhibited stable performance for seed yield per plant in different environmental conditions. On the other hand, crosses RT-346 x TKG-22, RT-346 x RT-351, TKG-22 x RT-372, TKG-22 x TC-25 and RT-372 x RT-351 indicated its suitability and stability under better environmental conditions. These crosses could be utilized as a promising breeding material for the development of new set of sesame varieties.
