At the stage of transfer to soil, a scheme is defined that provides production of improved plantlets of thestudied varieties. 'Kuharsky's Memory' and 'Kanakhama' black сurrant varieties are characterized by high regenerativecapacity in vitro (the proportion of viable explants is 93.5 % and 96.4 %, respectively). At the multiplication stage, the influence of growth regulators (6-benzylaminopurine, gibberellic acid) on the morphogenesis of currant plantlets was studied. It shows their impact on such morphological indicators of development of plantlets as the height (cm), quantity, theaverage length of roots (cm). At the rooting stage, the concentration (0.5 mg/l) of auxin (β-indolylbutyric acid) was selected, the introduction of which into the rooting medium provided the maximum indicators of rhizogenesis: the numberand length of roots.
