Abstract :
To evaluate of salinity tolerance indices in 17 commercial cultivars and 34 lines ofbread wheat against salinity of sodium NaCl, an experiment was conducted in growing season of 2012 in factorial experiment based on randomized complete block with two replications and in salt concentration of 0, 8 and 16 ds m in the greenhouse. In this study, total plant dry weight was measured. To assess the salt tolerance of genotypes stress susceptibility (SSI), tolerance (TOL), stress tolerance (STI), geometric mean productivity(GMP) and the mean productivity (MP) indices were used. In this study, regarding to the indices of MP, GMP and STI, Farahan 4452, Saruq 4468, Trfan4678, Parsi, Rezaieh 2745 and Nishapur genotypes identified to have the highest yield in both control and salt stress conditions. Therefore, they can be used in salineandnon-salineoruncertain areas, also because they had highbiologicalyield. On the other hand, it was observed that Roshan, MV-17, 22762, Zarea, 22919, Azerbaijan 2664 and Mahabad 1856genotypeshad the lowest rate of TOL and SSI indicesandthey can be grown in saline areasbecauseof having highbiological yieldin stress condition.
