Salinity is one of the major limitations in bread wheat production worldwide. Mutation breeding using gamma rays can be used to increase tolerance to salt stress. The current study was done to evaluate 15 bread wheat mutants under salinity stress conditions during the growing season of 2017-08 (M5 generation), 2018-19 (M6 generation), and 2019-20 (M7 generation). The results showed that wheat mutants had various reactions to salinity stress. Compared to control wheat cultivars (Arg, Bam, and Narin) M14 and M15 showed the highest grain yield and 1000-grain weight. Hence, these mutants can be considered as a promising salt-tolerant wheat mutant and can be used to release new salt-tolerant wheat cultivars.
