A cуtogenetic analysis of the cells of T. aestivum L. root meristem, whose seeds were grown on radio-nuclide contaminated substrates of bottom deposits of water reservoirs of the near alienation zone of Chornobyl NPP, was made. Frequency of chromosome aberrations exceeds the indices of spontaneous level by 1.6—3.3 times. Their type spectrum consists mostly of acentric fragments and bridges. The low frequency of revealed aneuplоіd cells can prove the availability of small concentrations of mutagenic factors in bottom deposits, which affect the apparatus of cell division and chromosome segregation. A significant increase of the index of aberration number per aberrant cell indicates the gravity of genetic after-effects of radionuclide contamination.
Keywords: Triticum aestivum L., cytogenetic violations, chromosome aberrations, bottom deposits, rаdionuclide contamination
