Three discrete trials were passed out under normal environment (E1), drought prone environment (E2) and salt stressed medicated environments (E3). The pooled analysis of variance for dignified traits of nineteen genotypes directed that environments were diversed and there were significant difference in genotypic retaliation across environments. Positive correlation of yield with normalized difference vegetation index at booting stage (stay green) and negative correlation with canopy temperature at booting stage (cooler canopy) in all environments advocated these as a dynamic yard stick for screening genotypes in the three environments. Relative water content of all genotypes significantly declined in E2 and E3 as compared with E1 at anthesis stage. Toward the yield stability of genotypes, E-1 was comparatively high contributor (discriminating) whereas E-3 was low contributor (least discriminating). Two genotypes were alike while three were unalike from the others due to their distance. Five genotypes stood winner in environment E1, two in E2 while three in E3. In all environments, two genotypes stayed adopted and stable, four stood adaptable with premier yield, two persisted stable with high yield, two existed stable by stumpy yield while all others presented no significant upshot. This nature of valuation will support in evolving new high yielding wheat varieties resistant to salinity and drought resilient.

Key words: Normal, drought, salinity, environments, diversity, steadiness, bread wheat.
