Results are reported on enhancing the efficiency of embryo culture for synthesizing primary hexaploid triticales (AABBRR, 2n = 42). The antioxidant tomatoside has a positive effect on the reduction of progamous incompatibility of wheat with rye and increases the output of wheat-rye amphihaploids. It has been established that irradiation of embryos, cultured on nutrient medium, with helium-neon laser, increases significantly (P < 0.01) the regeneration frequency of the wheat-rye hybrid embryos. The highest frequency (40%) of amphidiploids was obtained by treating the plants with 0.15% colchicine through roots during the tillering phase. Hexaploid triticales from 11 cross combinations between tetraploid wheats (AABB, 2n = 28) and diploid rye (RR, 2n = 14) formed the initial material for breeding.
