Interspecific distinctions on radionuclides accumulation depending on winter, spring wheat varieties and oats, reaching on 137Cs 1,7-3,1 times, on 90Sr - up to 2 times are revealed. Intervarietal distinctions on accumulation 137Cs at a winter wheat-1,7 time, at a spring wheat-1,6 time, at an oats-1,3 time, on accumulation 90Sr at winter wheat-1,1 times, at a spring wheat and at an oats - 1,5-1,6 times are established. Carried out research have allowed to recommend for cultivation in the polluted territories the zoned varieties which to the least degree accumulate radionuclides: a winter wheat - Bylina, Legend, Tsentos; a spring wheat – Kvattro, manu; an oats – Chakal, Dukat and Alph. These varieties can serve as an initial material for the further selection work on varieties breeding, steady against the raised environmental contamination. Varieties cultivation with the least values of factors of transition 137Cs and 90Sr on territories polluted by radionuclides is possible on soils in 1,6 times more polluted, than at varieties cultivation with high parameters of radionuclides transition. Yield, grain quality -protein and gluten was studied. Correlation relationships among transfer coefficients radionuclides 137Cs and 90Sr in grain of varieties, yield and potassium and calcium contents in grain was established.
