Background. Today, the effectiveness of berry crop cultivation depends on correct formation of the regional assortment of cultivars, taking into account the instability of environmental factors. Searching for and accumulating genetic resources from leading breeding centers, both domestic and foreign, as well as studying new genotypes under local conditions would make it possible to identify berry crop varieties for production and breeding.Materials and methods. This study was conducted in Michurinsk, Tambov Province, on the experimental plantations of red currant at the I.V. Michurin Federal Science Center in 2016–2020. The research material consisted of 15 introduced cultivars of red currant. Collection testing was carried out in line with generally accepted techniques of variety studies and field experiments.Results. Under the conditions of Tambov Province, the introduced red currant cultivars required a sum of temperatures of 89.3–132.0°C to start growing, 290.0–328.0°C to start flowering, 943.5–1133.0°C to start ripening, and 1478.2–1733.3°C to produce fully matured berries. Cvs. ‘Belosnezhka’, ‘Lvovyanka’, ‘Oksamit’ and ‘Rosinka’ showed complex resistance to diseases and pests. Cvs. ‘Kalinka’, ‘Lasunya’, ‘Lider’, ‘Lvovyanka’, ‘Oksamit’, ‘Orlovskaya zvezda’ and ‘Sara’ produced large fruits. Stable high productivity and yield were observed in cvs. ‘Vika’, ‘Lider’, ‘Oksamit’, ‘Orlovskaya zvezda’ and ‘Rosinka’. A close correlation (r = 0.99) was recorded between the productivity per bush (kg) and yield (100 kg/ha), and medium correlations between the berry weight and productivity per bush (r = 0.69), and between the productivity per one linear meter of branches and productivity per bush (r = 0.35).Conclusion. As a result of the integrated assessment under the conditions of Tambov Province, the red currant cultivars ‘Vika’, ‘Lider’, ‘Oksamit’, ‘Orlovskaya zvezda’ and ‘Rosinka’ were recommended for cultivation.

“…Например, во все годы, с благоприятными погодными условиями, сорта черешни проявляли одинаковую (характерную для каждого из сортов) способность к формированию максимально высокой урожайности. А в годы с проявлением негативных факторов наблюдали значительную разницу между показателями продуктивности сортов, поскольку в таких условиях урожайность сорта в большей степени определяла его генетическая способность противостоять неблагоприятным факторам внешней среды [11,12].…”

Comparative assessment of yield, commercial-consumer and tasting parameters of fruit quality of more than 20 introduced cherry varieties of different maturation periods grown in agro-ecological conditions of Dagestan foothills is presented. The most promising varieties, characterized by high yield, the best commercial and consumer and organoleptic properties, were revealed. Studies of quality indicators were carried out using generally accepted methods. It was determined that the mass of the fruit in the studied varieties averaged 6.4 g, and the maximum was 8.3 g (variety Krupnoplodnaya). In the group of middle-aged, with a fruit weight of 6.1-9.5 g, varieties of cherries of early ripening are assigned - Kosmicheskaya (6.6 g) and Valery Chkalov (7.0 g) and all studied varieties of cherries of early-middle and middle ripening, with the exception of varieties Melitopol'skaya rozovaya (5.3 g) and Melitopol'skaya rannyaya (5.4 g). All studied cherry varieties belong to the group of varieties with average sugar accumulation (8.89-11.85%) and acidity (0.65-0.89%). The highest tasting score (5 points) received the fruits of cherry varieties Kosmicheskaya, Valery Chkalov, Krupnoplodnaya, Melitopol'skaya chernaya, Vinka and Romantika, which during the research (2019-2021) showed a good ability to form a crop. A comprehensive assessment of the investigated introduced cherry varieties grown in the foothills of Dagestan showed that the most promising, characterized by high yields, the best commercial and consumer and tasting properties are the Kosmicheskaya, Valery Chkalov, Krupnoplodnaya, Melitopol'skaya chernaya, Vinka and Romantika varieties. These varieties may be recommended for further successful use in production and selection work in order to optimize the industrial variety of cherries

The results of the evaluation of the genetic collection of black currants on the multiple racemes trait for increasing the productivity of the crop in the conditions of the Bryansk region are presented. The index of the number of racemes with fruiting on one shoot node was studied. It has been shown that under the conditions of the southwestern part of the nonchernozem belt of Russia (Bryansk region), formation of one generative bud in the axils of leaves is typical for the crop, but there are forms in which some nodes are capable of forming 2-3 racemes with fructification. It has been found that out of 132 varieties of the genetic collection studied, 116 specimens (87.9%) formed nodes with 1-2 generative buds. As a result of the studies, varieties with 3-4 inflorescences on the nodes capable of bearing fruit were selected (Dar Smolyaninova, Debryansk, Bryansky Agat, Selechenskaya 2, Ladushka, Orlovsky Vals, Istok, Chudnoe Mgnovenie, Yubileinaya Kopanya, Vera, Chernavka, etc.). Their use in further crosses will produce more productive genotypes. The most productive combinations of the crosses have been identified according to the yield of progeny forming 2-4 generative formations on one node (63-35-1 × Litvinovskaya, Svityazyanka × Selechenskaya 2, Debryansk × Dar Smolyaninova, Chudnoe Mgnovenie × Golubichka, 10-141-2 × Partizanka Bryanskaya, Debryansk × Litvinovskaya). Promising selected forms (3-63-01, 5-82-02, 8-69-01, 5-45-02, 4-18-01, 4-94-1, 4-18-02, 2-30-01, etc.), which combine the multiple racemes feature with other economically valuable indicators (resistance to pathogens, large fruits, dessert taste of fruits, number of berries in the raceme, their one-dimensionality) are highlighted.
