The aim of the research is to search new sources of the main economically valuable traits for further breeding of raspberry. Nineteen previously created selected forms were studied for winter resistance components under controlled conditions, for resistance to major fungal diseases, productivity components, strength and biochemical composition of fruits. The zoned Gusar variety was used as the control. The work was carried out in 2018-2020 according to generally accepted techniques. Artificial freezing of raspberry stems was carried out in the climate chamber TH-6 JEIO TECH. According to the results of the studies, selected forms 8-10х-1, 6-125-4, which have an increased resistance to certain components of winter resistance, have been identified. Hybrids 2-115-1 and 1-188-1 have cumulative resistance to winter damage factors. Based on the integrated resistance of raspberry hybrids to the main fungal diseases, new sources have been revealed: forms 1-124-1, 2-115-1, 2-115-2, 1-111-21, 1-8-2, 2-35-1, 2-90-3, 6-125-4, 3-4-2, 8-10х-1, 4-33-21 and 4-122-2. The degree of their damage did not have a significant influence on winter hardiness, productivity and quality of berries. As the result of study of components of the raspberry productivity, selected forms (1-111-21, 2-90-2 and 2-90-3), forming fruits with an average weight of more than 4.0 g, and genotypes with large and one-dimensional fruits (1-176-21, 2-35-1, 4-33-21, 1-124-1) not growing smaller from picking to picking were identified. The highest potential productivity was noted for selections 2-115-1, 1-111-21, 1-188-1, 4-46-2, 2-90-2 and 2-90-3, capable to form a yield of more than 1.3 kg per bush. The selections 1-124-1, 2-90-2 and 2-90-3 are distinguished by an increased strength of the fruits. They form fruits with a crushing force exceeding 5.0 N, which ensures the safety of integrity and transportability when manually harvested. No complex sources of increased accumulation of biologically active substances have been identified. Genotypes with a high content of individual biochemical substances were selected. The highest accumulation of soluble solids and sugars was noted in the samples 2-90-3, 18-11-4 and 2-115-1. Highest accumulation o the vitamin C was observed in the samples 6-125-4 (59.8 mg/100 g) and 2-90-3 (61.5 mg/100 g). As new sources in breeding to improve the taste characteristics of raspberry, it is necessary to use selected forms 2-90-2, 2-115-1 and 6-125-4, approaching in taste to the standard variety Novost Kuzmina. Selected forms 2-90-2, 2-90-3 and 2-115-1 are new sources in raspberry breeding, combining a complex of economically valuable traits at a high level.

Thus far, the world’s blackcurrant range comprises about 1,200 varieties and is constantly being improved. The most successful breeding programs for black currant have been implemented in Poland, England, Belarus, Ukraine, Sweden, Lithuania, Finland, Romania, China and Russia. However, the climatic conditions of several regions of the Russian Federation make it difficult to fully realize the biological potential of foreign varieties and they often do not correspond to the characteristics declared by the breeder. The study is aimed at making comprehensive assessment of the introducers to establish their selection potential and the possibility of industrial cultivation. The study was conducted in 2018-2021 in the black currant collection site of the Kokino station of Federal Horticultural Center for Breeding, Agrotechnology and Nursery (Bryansk region). 20 varieties of black currant of foreign breeding from different ecological and geographical groups were explored. A new local variety Kudesnik with average maturation time was taken for comparison. It was included in the State Register for Selection Achievements in 2022. An assessment of introduced black currant varieties by morphological character of plants revealed the features of their growth in the south-western conditions of the central Non-Black Earth region. Varieties that do not meet the requirements of modern intensive mechanized technologies have been established. In terms of plant height, the varieties Mriya, Nympha, Kupalinka, Cheryshneva, Amethyst, Sofiyivska and Triton do not meet the parameters appropriate for mechanical harvesting. It will be difficult to use berry harvesting equipment with the varieties Sofievskaya, Amethyst and Klussonovskaya due to the wide base of their bushes (>0.3 m). The varieties Sofievskaya and Klussonovskaya, with the highest yield (10 t/ha) do not meet the requirements of modern production in terms of bush mien and berries tearaway force. The best introducers (Sofievskaya, Klussonovskaya, Nympha, Mriya, Cheryshneva, Triton, Belorusochka, Kupalinka) with a yield of 8.3-10.0 tonnes/ha can be recommended for home gardening. A number of foreign varieties as genetic sources in breeding for berry strength (Cheryshneva, Ben Hope, Black Magic, Tiben); fruit size (Nympha); number of fruits in the claster (Triton, Cheryshneva); taste qualities (Mriya); high content of soluble solids (Ben Tirran, Sofievskaya, Mriya) and other characteristics of interest have been identified.

The article presents research findings on the weight of black currant berries. The research focused on the varieties and selected forms of black currant (Ribes nigrum L). Nara variety, adapted to local conditions, was used as a control. Studies were carried out in 2020–2022 at the plots for genetic collection and competitive trials of selected forms of black currants at the All-Russian Research Institute of Lupin (Bryansk region). The planting scheme involved a spacing of 3×0.8 m on grey forest soils. The observations were carried out using conventional methods. The varying weather conditions during the study period allowed for a more objective evaluation of the genotypes in terms of their adaptive capabilities and facilitated the selection of large-fruited and resistant forms. The most favourable meteorological conditions for berry weight development were observed in 2022. During this period, the average berry weight of the studied gene pool was 2.5 g. Among the examined varieties, Dobrynya (3.5 g), Debryansk (2.7 g), Chara (2.6 g) and Selechenskaya 2 (2.6 g) demonstrated the largest berry sizes with variation coefficients of 20%, 28%, 7%, and 17%, respectively. Large-fruited forms having an average berry weight exceeding 3 g and high stability (V=3%) were selected from the hybrid family 6-12- 224×6-26-207 – 7-3-227 (3.6 g), 7-3-213 (3.4 g), 7-19-100 (3.6 g) and Selechenskaya 2×Treasure – 6-20-67 (3.5 g). These genotypes represent valuable parent material for further breeding aimed at increasing berry weight. New large-fruited sources with a combination of important breeding traits (large fruit, high vitamin C content, resistance to powdery mildew and bud mite), namely,7-19-100, 7-3-227, 7-18-250, 7-13-232 and 7-17-150, were identified. The variety Dessert Olkhina exhibited the smallest berries (0.8 g) with a variability of 20%. The influence of weather conditions on the weight of berries was established, revealing a positive average correlation between berry weight and precipitation levels from May to July (r=0.52) and the hydrothermal index of the growing season (r=0.56).
