Most of the crop salt tolerance studies are often conducted in a glasshouse and are limited under field conditions. Therefore, the present research study was conducted under field conditions to evaluate the performance of six wheat cultivars at five salinity levels (EC 0, 3, 6, 9, and 12 dS m⁻¹) in split plot design with three replications. Increasing salinity significantly increased soil pH, electrical conductivity (EC), and sodium adsorption ratio (SAR). Yield parameters of different cultivars were affected more at higher salinity levels than lower in two years. Data over two years revealed that up to EC 9 dS m⁻¹ cultivars PBW 658 and HD 2967 performed better on the absolute yield basis but PBW 621 produced higher relative yield. At EC 12 dS m⁻¹, PBW 658 produced significantly higher grain yield (4.23 t ha⁻¹) than cultivars HD 2967 (4.11 t ha⁻¹) and PBW 621 (3.99 t ha⁻¹); therefore, should be preferred at salinity more than 9 dS m⁻¹.
