The highest activity by chromosome aberration frequency had EI 0.025 and 0.05
percent concentration in Myronivska 25 variety, and under different concentrations
in Kiyanka. The lowest number of violations of chromosome structure caused NMB
under all concentrations in Kiyanka variety, and in Poliska 70 and Krasnodarska 46
varieties, it was the third by this feature.
