The production of strawberry planting material using the method of clonal micropropagation of plants is promising, modern and already widely used. This paper presents the results of assessing the breeding potential of garden strawberry varieties Nelly and Kemiya (selection of FSBSI NCFSCHVW) in in vitro culture. Apexes from growing rosettes of strawberries served as the starting material for the initiation. The best survival rate of explants was noted during the initiation in the second decade of August, which were in Nelly variety - 90%, Kemiya - 83.3%. At the stage of proliferation, 6-Benzylaminopurine (6-BAP) was injected into the culture medium at various concentrations (0; 0.5; 1.0 and 1.5 mg / L). To increase the efficiency of micropropagation of strawberries Nelly and Kemiya varieties, it is advisable to add 6-BAP into the culture medium with the amount of 1.0 mg / l. In this variant, 10.6 shoots were formed in the explants in Nelly variety, 5.9 in Kemiya variety. With an increase of the concentration of 6-BAP to 1.5 mg / l, the number of vitrified shoots were raised. According to the results of three subcultures, it was noted that the Nelly variety has a higher reproduction potential compared to the Kemiya variety. At the stage of rhizogenesis, the addition of auxins to the medium was not required, since the roots of regenerated plants formed independently.
