Charmo, Maroof, and Alla are new promising rust-resistant wheat varieties were had been tested for their salinity tolerance through seed water uptake, germination percentage, and germination mean, as well as the growth of radical and plumule. The varieties were tested for their salt tolerance level by using salt solutions concentration levels with a control, 0.01, ,0.03.0,05, 0.07, and 0.09 mol, which are the answer to 0.0, 0.58,1.75,2.9,4.01 and 5.26 gL -1, that symbolized as C0, C1,C2, C3, C4and C5, which are equal to 0.9, 2.7, 4.6, 6.3, and 8.2 EC dS m−1 respectively.. The results showed significant effects of varsities on water uptake, germination percentage germination meantime, and wet and dry radicals, but no significant effect on radical number and length as well as plumule length and wet dry plumule. What is concerning the effects of salt levels on germination parameters and growth of seedlings, noted a significant effect of salt on germination meantime, germination percentage, growth radical and plumule length as well as on wet radical weight. And the interaction between varieties and salt levels, result has shown a significant effect of the interaction between varsities and salt levels on dry radical weight. Salt levels from C3 have indicted to have a significant effect on the germination of wet radicals but not a significant effect on water uptake, dry radicals, as well as on wet and dry plumule. The results of the effect of varieties on germination and growth parameters showed, that charmo and maroof are better than Alla, Charmo, and Maroof are tolerating C2 –C3/ 4,6 dS m−1 -6.3 dS m−1 but Alla does not, which is why it cannot be recommended to be used in soil with EC 4,6 dS m−1 which answers to C2.
