Both non-irradiated and irradiated calluses were divided into about 1 mm. in diameter and proliferated onto non-saline and saline CI medium for three consecutive phases with interval of 45 days. Four electrical conductivity (EC) levels of NaCl (4.0, 6.0, 8.0 and 10.0 d/Sm) were established in CI medium with the same amount of 2, 4-D, sucrose, bacto agar and with similar culture conditions. CI medium was replaced with fresh medium at each proliferation phase. Growth of tissue was expressed by value determined by the ratio of final weight to the initial weight. Calluses with maximum growth value were used as source of inocula in the next phase. Thus adapted callus lines at different EC of NaCl were obtained. Finally all adapted calli were transferred to MSR medium (modified MS medium containing MS salts and vitamins supplemented with kinetin, 9.2
