The shade tolerance of black currants (Ribes nigrum cv. Consort) was studied by measuring the growth and productivity of mature plants in the field for three seasons under full sun or artificial shade netting in Urbana, IL. Shade treatments reduced photosynthetically active radiation (PAR) from 37% to 83%. Yield was not reduced in shade levels up to 65% but decreased by as much as 66% under 83% shade. Shade had minimal effect on stem rejuvenation in the first 2 years, but reduced rejuvenation in the third year from 14 new stems in full sun to eight new stems in 83% shade. Stem diameter decreased 8% to 19% with 83% shade, whereas no changes were observed in up to 65% shade. Plant height increased 5% to 8% from open sun to 83% shade. Specific leaf weight decreased and leaf area increased with shade. Powdery mildew severity increased with shade, and disease-resistant cultivars should be considered for understory crops. Our results indicate that growth and productivity of black currants can be maintained in moderate shade but shade levels beyond 65% will significantly reduce agronomic performance.

The main goal of the scientific institution was and remains to improve the assortment of fruit and berry crops for the development of domestic horticulture. Black currant breeding at VNIISPK was started by A.F Tamarova and continued by the doctor of agricultural Sciences T.P.Ogoltsova and doctor of agricultural Sciences S.D. Knyazev. A long-term breeding program has been developed. The main goals of the program are to create black currant cultivars with continuous resistance to diseases, first of all powdery mildew, as wells resistance to pests, i.e. bud mite. As a result of the long-term work, over 40 black currant cultivars have been developed, 14 of them are zoned. Red currant breeding was led by the candidate of agricultural Sciences L.V. Bayanova; since 2001 the work has been continued by the candidate of agricultural Sciences O.D. Golyaeva. ‘Heinemanns Rote Spӓtlese’, the descendant of R. multiflorum Kit., was involved in the red currant breeding for the first time in Russia. On its genetic basis, a series of late maturing cultivars with long and dense racemes was created. At the Institute, in total 21cultivars of red currants have been developed, 13 of them are zoned. At present, red currant cultivars make up 25.5% of the zoned assortment in Russia. The first research on gooseberries was stated by V.P. Semakin and A.F Tamarova; since 1992 the systematic gooseberry breeding has been carried out by the candidate of agricultural Sciences O.V. Kurashev. On the basis of Grossularia robusta, we have created gooseberry forms that are resistant to powdery mildew and leaf spots. These forms are highly productive, weakly thorned, having bush habit suitable for mechanized harvest. The result of breeding activities was the transfer of 6 gooseberry cultivars to State agricultural testing: ‘Solnechny Zaychik’, ‘Nekrasovsky’, ‘Yupiter’, ‘Zemlianichny’, ‘Moryachok’ and ‘Discovery’.

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.

The article presents the main results of twenty years of research carried out at the Federal Horticultural Research Center for Breeding, Agrotechnology and Nursery (Kokino Base Station) on the search and creation of various genetic origin genotypes and the possibility of their use in further breeding work on black currants. The created genetic sources of resistance to American powdery mildew, leaf spots (canker, septoria, cercosporosis), large-fruited, berries’ high vitamin С content, fruit strength, plant productivity are presented: 7-37-2 (Litvinovskaya × Dar Smolyaninovoy), 37-27-4/05 (Debryansk, free pollination), 63-35-1 (Lentyay × Debryansk), 68-03-1 (Charodey × Yadryonaya), 5-66-5 (Dobrynya, free pollination), 13-51-1 (Shalunya, free pollination), 33-27-1 (Strelets × Selechenskaya 2) etc. As a result of breeding research, 12 black currant varieties have been created, eight of which (Bryanskiy Agate, Debryansk, Mif, Vera, Gamayun, Strelets, Charodey, Barmaley) are included in the State Register of Breeding Achievements, approved for using.

Chemical characteristics of fruit spirits produced from three black currant cultivars (Malling Juel, Ometa, Ben Sarek) and two red currant cultivars (Rondom and Versailles) grown in Serbia were examined using gas chromatography. In addition, sensory evaluation of the spirit samples was performed using the Buxbaum model of positive rating. Fruit spirits produced from black currant cultivars displayed the highest contents of methanol (267.2 - 595.0 g/hl A. A) and amyl alcohols (74.2 - 204.8 g/hl A. A). Total sensory scores of currant brandies ranged between 17.60 and 18.40, while currant brandy produced from Ben Sarek black currant cultivar received the highest score (18.40). All tested samples of currant brandies fulfilled EU requirements as regards their content of methanol and other components such as acetaldehyde, ethyl acetate and high alcohols. The currant distillates were compared with other commercial spirits, including plum and grape brandies.

The aim of this study was to evaluate the effects of black currant (Ribes nigrum L. ‘Ben Sarek’) juice on the blood pressure and frequency of cardiac contractions, as well as vasomotor responses of rat aortic rings. Arterial blood pressure was measured directly from the carotid artery in the anaesthetized rabbits. The aortic rings were pre-contracted with KCl (80 mmol·L−1), after which black currant juice was added. An intravenous injection of black currant juice (0.33–166.5 mg·kg−1) induced a significant and dose-dependent decrease of rabbit arterial blood pressure and heart rate. The black currant juice decreased arterial blood pressure of rabbit by 22.33% ± 3.76% (p < 0.05) and heart rate by 17.18% ± 2.93% (p < 0.05). Cumulative addition of the black currant juice (0.01–3 mg·mL−1) inhibited concentration-dependent KCl induced contractions of the isolated rat aorta. The black currant juice, at the concentration of 3 mg·mL−1, caused a maximum relaxation of 21.75% ± 3.15% (p < 0.05). These results demonstrate that black currant juice can induce hypotension. The hypotensive effect of the black currant may occur as the consequence of its inhibitory activity on the rate of heart contraction and vasorelaxant effects.
