The genetic development for salt tolerance in wheat is very important approach for the plant breeder to overcome salinity problem. Estimation of salt tolerance by two selected genotypes of wheat (4H, N5) was conducted in plastic house as compared with the local cultivars Tamoz 2 to know the development that happened in salt tolerance in these genotypes through the plant breeding programs. The experiment was conducted in pots using four salinity levels (2, 5, 10, 15)ds/m. The experimental design was RCBD with three blocks. Results indicated that both selected genotypes were significantly superior in all measured characters to check cultivar at all salinity levels. There were differences between the two selected genotypes in different traits, but not significant especially at high salinity levels. At these salinity levels, the selected genotypes had more growth in shoots and roots. The differences between the two selected genotypes and the check cultivar in all characters increased in high salinity level. In conclusion, there were genetically improvements with aspect to salt tolerance achieved in selected genotypes through breeding and improvement programs.
