The present investigation was carried out to study stability performance over three locations for fruit yield and its components using Line x Tester mating design. The crossing programme was carried out during late kharif season of 2019-2020. The evaluation of F1 hybrids was done at three different locations in late kharif season 2020-2021. The experiment was conducted in Randomized Block Design (RBD) with three replications which included 40 genotypes comprising of 7 lines, 4 testers, their resultant 28 hybrids and one standard check GNRB^-1. The analysis revealed that genotypes × environment (G×E) interactions were significant for most of the traits except plant height at final harvest, total number of branches plant^-1, fruit length, number of fruits plant^-1, fruit yield plant^-1, number of seeds fruit^-1 and TSS when tested against pooled error and pooled deviation. Among parents, NBL-117 and GNRB-1 showed above average stability and specifically adapted to unfavourable environment for total fruit yield ha^-1. Among crosses NBL-117 × Swarna Mani and NBL-117 × GNRB-1 exhibited their stability under unfavourable environments. The crosses NBL-117 × GAOB-2, NBL-117 × GOB-1 exhibited its suitability and stability under favourable environments. However, none of the genotypes were found to have average stability for total fruit yield ha^-1.
