At interaction of chemical mutagen of dimethyl sulfate (DMS) with genotypes of winter wheat Favoritk, Lasunya, Khrutovina, Kolos Mirovnovschiny, Sonechko, Kalinova, Voloshkova and lines 418 the features of mutations induction have been investigated. The variation of the mutations frequency according to the concentration of DMS (0.0125, 0.025 and 0.05%) and the genotype processed by the mutagen was established. It was shown that in all genotypes the highest frequency of mutations was observed at DMS action in 0.05% concentration. The variation range of the mutations frequency at the specified concentration from 18.0% (Khrutovina breed) to 28% (Voloshkov breed) was determined. Dimethyl sulfate use in 0.0125% concentration as the optimum variant of winter wheat plants processing for obtaining selective-valuable mutations was substantiated. DMS using in 0.05% concentration to increase the release of genetically-valuable mutations in winter wheat breeds and lines was recommended
