Breeding opportunities for increasing the black currant large-fruiting

The results of the study of the black currant varieties collection of FSBSI FRC of Horticulture, located in the Bryansk region, by large-fruiting are presented. Genetic sources have been identified for inclusion in the breeding process to increase the average weight of berries (Lentyai, Titania, Gamayun, Dobry Gin, Podarok Veteranam, Podarok Astakhova, Kudmig, Debryansk, Bryanskiy Agat, Dar Smolyaninovoy, Kudesnik, and others). The most productive families for the output of large-fruited seedlings are given, such as Debryansk × Dar Smolyaninovoy, Orloviya × Nara, Rita × Titania, Strelets × Partizanka Bryanskaya, 10-141-2 (Strelets × Golubichka) × Partizanka Bryanskaya. The result of well-chosen combinations of crosses was the creation of new highly productive varieties of black currant Mif, Favorit, and several selected forms.
