Current trends in the development of the horticulture industry have shown that in order to meet the needs of the Russian population for fruits and berries, it is necessary to expand the plantations of these crops. Clonal micropropagation is a modern method of mass, accelerated vegetative propagation of plants, which is widely used in the production of domestic planting material for garden plants. However, given that most of the nutrient media used today in the practice of clonal micropropagation were created in 70–80 years of XX century, there is a need to improve its optimal compos ition.

The article presents the results of research on clonal micropropagation of sour cherry (Prunus cerasus L.) which is difficult to reproduce at the proliferation stage by traditional methods. A number of modern winter-hardy domestic cultivars of P. cerasus are promising for plantation cultivation of this crop in the Nonchernozem zone of the European part of Russia. The method of clonal micropropagation is advisable to obtain a large amount of healthy and genetically homogeneous rootstocks of fruit crops. Regenerated plants of P.
