Micropropagation of Chrysanthemum is an alternative to the traditional method of reproduction. Thanks to this method, the Chrysanthemum reproduction time is reduced to 3-4 months. For clonal micropropagation, sterile microshoots of Chrysanthemums of the varieties Snow White, Stranger, and Baltica White were used. At the stage of the micropropagation, the Murashige-Skoog (MS) medium with the full and half composition of mineral salts and growth regulators (kinetin, 6-benzylaminopurine, β-indolylacetic acid) were used. A universal culture medium for clonal micropropagation of all varieties of Chrysanthemum and optimal mediums, taking into account variety-specificity were established. It was noted that under in vitro conditions, high proliferative activity was observed in Neznakomka variety.
