“…Многочисленные исследования подтверждают высокие показатели содержания аскорбиновой кислоты в плодах черной смородины, произрастающей на территории Республики Саха (Якутия), особенно дикорастущей, -до 4000 мг/100 г [2,7,15,16]. Д. М. Уваровым и Н. К. Чириковой были получены данные содержания фенольных соединений -235,55 ± 0,76 мг/г [17], указывающих на превосходящее содержание фенольных соединений в плодах черной смородины, произрастающей на территории Республики Саха (Якутия) [8].…”

Antioxidants in plants have specific organ and tissue tropisms and different points of application. The physiological realisation of antioxidant effects is closely related to the chemical and spatial structure of their molecule: each functional group within the molecule has a specific molecular target - a kind of “point of activity”. This approach opens up the prospect of developing new, more effective antioxidants [1]. Black-fruited berries are an excellent source of the pigments anthocyanidins - polyphenolic compounds with unique antioxidant activity - ascorbic acid and other essential vitamins. Dark berry seeds are rich in unsaturated fatty acids. At the same time, berries have a unique composition of micro- and macroelements such as potassium, magnesium, zinc, manganese and copper, which are active participants in the redox reactions of the body and ensure the work of all links of the antioxidant defence of the body [2]. Among all dark berries, the fruits of black currants and their relatives have not only a higher content of ascorbic acid and a rich mineral composition, but also the densest skin, which accumulates the most promising antioxidant group of polyphenols - anthocyanidins. Such a combination on the principle of synergism represents the prospect of high efficiency of antioxidant action of the phytocomplex. The aim of the research was to determine the content of biologically active substances in the fruits of the wild currant Ribes dikuscha Fisch. Furthermore, the morphometric parameters of R. dikuscha fruits were described as a function of growing location. In this research, for the first time the content of biologically active substances with antioxidant properties in the fruits of Ribes dikuscha Fisch. was studied; also, a comparative analysis of biologically active substances and morphometric parameters of the R. dikuscha fruits depending on growing places was conducted. It was concluded that there was a negative correlation between the size of the fruits and the total content of low-molecular antioxidants in the berries; on the contrary, there was a positive correlation between the thickness of the outer skin of the fruits and the quantitative content of polyphenolic compounds in Ribes dikuscha Fisch.

The results of the study (2016–2018) of the blackcurrant initial breeding material in yield, winter hardiness, resistance to powdery mildew and blackcurrant gall mite in Central Yakutia are presented. The observations were carried out in a breeding garden with a planting scheme of 2 × 1 m. Objects of the research were 90 hybrids of blackcurrant. The studied hybrid forms were divided into 5 genetic groups of different origin, obtained from intercultivar, intraspecifi c, and interspecifi c crosses of descendants of the European (Ribes nigrum ssp. Europaeum (Jancz.)) and Siberian subspecies of blackcurrant (R. nigrum ssp. Sibiricum (E.W.)), Scandinavian currants (R. nigrum ssp. scandicum Hedl.), wild currants (R. dikuscha Fisch. ex Turcz.), few-fl owered currants (R. pausifl orum Turcz. ex Pojark) and recumbent currants (R. procumbens Pall.). The most winter-hardy in the sharply continental climatic conditions of Yakutia are hybrids in the families of the Altaiskaya Late × Yakutskaya (1-2-13), Altaiskaya Late × Lucia (15-13), Podarok Kuzioru × Hara Kytalyk (1-1813, 2-2-13, 2-4-13, 2-16-13), Podarok Kuzioru × Lucia (4-9-13). Resistance to blackcurrant gall mite was shown by hybrid families Altaiskaya Late × Yakutskaya, Altaiskaya Late × Hara Kytalyk, Altaiskaya Late × Lucia, Lama × Hara Kytalyk, Nika × Hara Kytalyk, Sharovidnaya × Hara Kytalyk. American powdery mildew did not affect 78 out of 90 plants of blackcurrant. The hybrids 3-4-13 (Podarok Kuzioru × Hara Kytalyk), 5-13-13 (Sharovidnaya × Hara Kytalyk), 3-11-13, 3-13-13 (Podarok Kuzioru × Pamyati Kyndyla), 516-13, 5-17-13 (Sharovidnaya × Pamyati Kyndyla were characterized by high yields (from 12.5 to 19.4 t/ha). The forms distinguished by individual characteristics can be used in further blackcurrant breeding as sources of economically valuable traits. Hybrid forms 3-4-13 (Podarok Kuzioru × Hara Kytalyk) and 3-6-13, 3-13-13 (Podarok Kuzioru × Pamyati Kyndyla) are of interest as complex sources of high yield, resistance to powdery mildew and blackcurrant gall mite.
