Timeliness. Currently, the Russian Federation has a high demand in healthy planting material of garden strawberries. The benefits of using fertilizers when growing strawberry seedlings have been proven by numerous studies. However, a comparative study of the effect of new fertilizers and methods of their application is very limited. In this regard, studies aimed at identifying the effectiveness of the use of prolonged-acting fertilizers in the production of garden strawberry planting material in protected soil conditions are relevant.Methods. Adapted to non-sterile conditions, ex vitro healthy garden strawberry plants were planted in a peat substrate of Veltorf LLC (recipe No. 5c/2) with the addition of Pg mix starter fertilizer with the structure NPK 14-16-18 + microelements (1.5 g/l of substrate). At the same time, prolonged-acting fertilizers were introduced into the substrate in the recommended concentrations: FertiPro Gran 1M (1.25 g/l of substrate), Ruscote 5-6M (3.0 g/l of substrate), Basacote Plus 6M (4.0 g/l of substrate), control peat substrate without fertilizers, PG mix standard.Results. It has been established that for the Karmen crop with an average runner-forming ability, the effectiveness of applying FertiPro Gran 1M fertilizer to the substrate was revealed, with the use of which, on the 180th day of cultivation, the number of runners and rosettes increases by 3.5–3.8 times compared to the control. At the same time, the yield of marketable seedlings is 95% compared to 70% in the control. For the Jūnija smaids crop with a high vine-forming ability, the effectiveness of all experimental variants with the application of FertiPro Gran 1M, Ruscote and Basacote Plus fertilizers to the substrate was revealed, with the use of which, on the 180th day of cultivation, the number of runners and rosettes increases by 1,9-2,5 times compared to the control. At the same time, the yield of marketable seedlings is 94-96% compared to 65% in the control.Conclusion. The introduction of long–acting fertilizers FertiPro Gran, Ruscote and Basacote Plus into the peat substrate with the addition of Pg mix starter fertilizer allowed a 2.3 – 3.8-fold increase in the number of runners obtained and 1.9-3.5-fold increase in the number of sockets obtained compared to the control without fertilizers.

Results of phenotypic evaluation of black currant genetic collection, selected forms, inbred and hybrid progeny by shrub habitus are presented. The possibility of using promising genotypes to produce the progeny with an optimal type of crowns was studied. Studies were conducted in 2017- 2021 in the conditions of the Bryansk region in the plots of the genetic collection, competitive study of selected forms, and hybrid black currant stock. The cultivation of black currants in the collection plantations and on the hybrid plot was carried out in accordance with the common in the Non-Black Earth Zone of Russia agro-technique. The weather conditions of the Bryansk region are typical for the Central region of Russia, the climate is moderately continental. Differentiation of varieties and selected forms by crown shape of plants was carried out. Hybridological analysis of inheritance of shrub habitus trait on the example of nine families from controlled crosses, three populations from self-pollination of genotypes different in shrub shape and three - from free pollination of promising black currant genotypes was performed. Varieties corresponding to the individual parameters of combine berry harvesting technology in terms of shrub habitus, base width, plant height were identified. These include the varieties Litvinovskaya, Myth, Rita, Kudesnik, Kudmig, Ben Hope, Nezhdanchik, Podarok Astakhova, Tamerlan, Tiben, Etyud, Chernavka and others, as well as a number of promising hybrids - 4-94-1, 3-80-01, 4-5-2, 4-19-04, 62-03-7, etc. The phenotypic evaluation of black currant progeny showed that the manifestation of the shrub habitus trait has a significant dependence on the crown type of the genotypes involved in the breeding work.
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.
