CURRANT, GOOSE, RASPBERRY, CEREALS, VIBURNUM, HYBRIDIZATION, COMBINATION OF CROSSINGS, SEEDLING, HYBRID, VARIETY. The object of research are varieties and hybrid forms of berry crops. The purpose of the work is to identify sources and donors of economically valuable traits of berry crops as a result of analysis of the degree of inheritance in hybrid generations of different combinations of crosses and selection of forms with high productivity, quality of berries resistant to biotic and abiotic environmental factors. Research methods - field, laboratory. In 2016-2020, artificial hybridization was performed in 133 combinations of crosses. 46221 flowers were pollinated, 1844 pieces were obtained. berries from hybridization and sown141116 pcs. hybrid seeds. The hybrid fund at the end of 2020 was 3380 seedlings. During the reporting period, nine promising hybrid forms of black currant, seven forms of gooseberry, six forms of raspberry, currant and viburnum were selected; There are seven forms of black currant, five forms of raspberry and currant, four gooseberries and six forms of viburnum. Studies on the degree of berry tying, seed formation in berries during artificial hybridization in different combinations of crosses, the peculiarities of growing hybrid seedlings of different genetic origin, evaluated the yield, quality of berry harvest in selected promising and elite hybrid forms of berry crops. Sources of valuable traits for further selection work have been identified and two varieties of black currant and one variety of gooseberry, raspberry and viburnum have been created. Methodical recommendations on selection of berry cultures are developed. Field of application - berry growing. Terms of receipt of the report: under the contract.
