The results of the studies of variation of some quantative features in two varieties of Chrysanthemum × hortorum Bailey. under the effect of dimethylsulphate are presented. The inbred progeny of K-82 varietal sample and hybrid progeny of ‘Gebe’ variety were employed for the trial. Differences in variation of features in the first and second year of vegetation in either variety were revealed. The optimum doses of dimethylsulphate for the use in selection of chrysanthemum were determined.
