Effects of irradiation of dry F1 seeds with gamma rays in the dose of 200 Gy were studied. Hybrids between near-isogenic lines on the basis of the variety Bezostaya 1 served as the material of investigation. Irradiation markedly reduced productivity traits of F1 plants and did not affect the survival of F1 plants under the given growth conditions. A significant relative increase in the frequency of pollen grains with the 1BL/1RS translocation that formed F2 seeds in comparison with the control was one of the effects of irradiation of F1 seeds. Irradiation with gamma-rays induced mutations at gliadin loci with the frequency of 7,4 % (at 0,5 % in the control).
