The study evaluated the productivity ofGossypium barbadenseL. genotypes under drought and salinity. ANOVA was used to analyze yield parameters of 10genotypes under optimal, water-deficient, and saline conditions. Genotypes T-479 (23.01 g) and T-2090 (21.72 g) showed high drought tolerance, while Duru-gavhar-4 (15.98 g) and T-2024 (15.54 g) exhibited salinity resilience. Environmental factors accounted for 79% of yield variability. Stress-tolerant genotypes are recommended for breeding programs to develop adaptive cotton varieties
