The article presents data from the effectiveness studies of the initial introduction stage of black currant (Ribes nigrum L.) into in vitro culture depending on the introduction period and the corresponding climatic conditions. The research objects were varieties of black currants selected by the Russian Research Institute of Fruit Crop Breeding: Azhurnaya, Orlovskaya serenada, Ocharovanie, Chudnoye mgnovenye. The introduction into in vitro culture was carried out in several periods characterized by different physiological states of the explants: the period of dormancy release (mid-March), the period of active growth (June), and the period of growth decay (mid-September). The source material in the spring and autumn periods were the buds of one-year stiffened shoots, in the summer introduction period - the buds of growing green shoots. The cultivation was carried out on Murashige-Skoog medium supplemented with 6-BAP (0.5 mg/l). It was noted that the survival rate of explants is determined by the physiological state of the source material due to the corresponding agro-climatic conditions during the introduction period, as well as the genotypic characteristics of the varieties. Thus, explants isolated during the active growing season are characterized by a higher and more stable survival rate. When explants were cultivated in spring and autumn, the physiological state of the explants and their survival rate were influenced by the genotypic response of varieties to the corresponding agroclimatic conditions.

The antifungal activity of water extracts of dried leaves of folded blackberry (Rubus plicatus W. et N.), walnut (Juglans regia L.), black currant (Ribes nigrum L.), and aspen (Populus tremula L.) was assessed in the in vitro experiment. The tested fungi were Alternaria alternata, Botrytis cinerea, Rhizoctonia solani, Fusarium culmorum, F. oxysporum and F. solani. It was found that all tested extracts inhibited the development of A. alternaria and F. oxysporum, whereas the strongest inhibiting effect was exhibited by extracts of aspen (A. alternata and F. oxysporum), black current (A. alternata) and folded blackberry (F. oxysporum). The tested extracts had no effect on B. cinerea.

Rooting Medium

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.

The article highlights the results of research carried out in 2019-2020 to study the reasons for the drying out of the stems of black currant (Ribes nigrum L.), red currant (Ribes rubrum L.) and golden currant (Ribes aureum L.). As a result of research, the fungus Sphaeropsis malorum Peck. in the first in Russia it was revealed from the drying stems of three types of black currants, red currants and golden currants. This  pathogen inhabited currant stems together with fungi from the genus Cytospora spp., causative agents of stem drying. On red currants, it was established that S. malorum was the main causative agent of branch drying, as indicated by the high frequency of occurrence (75.0-83.3 %) of this fungus on the affected stems, compared with species from the genus Cytospora spp. (16.7-33.3 %) and Phomopsis ribesia (25.0 %). Due to the fact that the cultivation of currants in the immediate vicinity of apple and pear trees leads to infection of plants with the fungus S. malorum, it is necessary to avoid planting currants in the vicinity of fruit-bearing seed gardens.
