In this study 31 doubled haploid wheat promising lines along with the parents and 4 salt tolerant wheat cultivars were evaluated using alpha lattice design in 3 replicates. The soil and water electrical conductivity in each location was between 8 to 11 ds m-1 and 4.8 to 9.35 ds m-1, respectively. The studied traits measured throughout the growing season were as stand establishment percentage, reaction to the diseases of the locations, number of days to spike initiation and maturity, plant height, grain loss percentage, grain color, thousand grain weight and grain yield.Evaluation for the tolerance of the lines was based on their suitable agronomical traits, mean grain yield, ranking and standard deviation comparing to the local check genotype. The locations mean grain yield for doubled haploid genotypes of 16, 28 and 29 were 3.3, 3.5 and 3.3 t ha-1, respectively which were more than or equal to the local check mean grain yieldof each location, while grainyield of 12 other genotypes was also more than 2.8 t ha-1 which were selected for suitable plant height, thousand grain weight more than 40 g, disease and grain loss resistance. For instance in lines 8 and 12, thousand grain weight was more than 50 g and the plant height was higher than 85 cm having good remobilization potential in terminal growing season.
