Abstract

Salt-tolerant mutants of potato (Solanum tuberosum L. 'Marfona') were obtained via gamma irradiation. Node explants of the Marfona potato plant were treated with various dosages of gamma irradiation, and the M_1V_2 and M_1V_3 clonal generations were developed. Selection of salt-tolerant mutants was accomplished by in vitro selection media containing 50, 100, and 125 mM NaCl. Molecular-level differences between the control and mutant plants were elucidated using RAPD-PCR method, and the polymorphism rate according to the selected primers was calculated as 89.66%. Genetic distances between the controls and mutants were also calculated, and related dendrograms were produced. On average the mutants were genetically 27.5% different from the control plants. The greatest difference encountered between the control and mutants was 47%, which was detected in mutant plants produced by 20 or 30 Gy gamma irradiation and regenerated in selection medium containing 100 mM NaCl.
