Resistance to diseases and pests is one of the main tasks of a breeder when creating varieties of cultivated plants. On perennial plants, which include black currants, diseases have a significant impact on the quantity and quality of the formed yield, as well as on the laying of the subsequent yield. Constant screening of new breeding material allows not only to select and isolate promising highly resistant forms at the early stages of ontogenesis, but also, as a result, to speed up the entire selection process of creating immune varieties. As a result of our research, we found that the bulk of the studied hybrid seedlings in 2019-2020 were resistant to American powdery mildew and columnar rust.
High resistance to American powdery mildew is characteristic of derivatives of glutinous currant and the Scandinavian subspecies of black currant. Also, the derivatives of glutinous currant are characterized by high resistance to columnar rust.
