Qualitative assessment of hybrid forms of blackcurrant (Ribes nigrum L.) of Bashkir breeding

Abstract

The article presents  qualitative  assessment  of  the  selected  blackcurrant  hybrids,  bred by Ufa Branch of the Russian Academy of Sciences for potential and stable yield and resistance to pathogens and pests. It was found that the hybrids differed in a number of traits and were identified as sources of economically valuable traits for further use in breeding work. When analyzing the hybrid families, it was found that the hybrids of Karaidel and Valovaya, Valovaya and Bredtorp, Chishma and pollen mixture, Valovaya and Chishma produced more productive offspring were obtained, and the highest average yield was from 15.0 to 15.2 t/ha over 5 years in hybrids No. 15–19 and No. 3–42. In terms of large fruit size, with an average berry weight of more than 2.5 grams, the following varieties stood out: 1–9–99, 7–36, 1–9–92, 1–9–91, 1–9–102, 3–26. The selected varieties have large berries with a maximum weight of up to 3.0–4.5 g, while the control variety Valovaya, has a maximum weight of 2.5 g. The most resistant to anthracnose are hybrid forms: 5–19, A-4, A-9, A-10, A-12, A-22, A-6, 1–9–66, 1–9–88, 1–7–86, 3–42, 3–46, 3–48, 7–36, 10–14; 
the most resistant to aphids: 3–22, 5–11, 4–16, 1–9–99, 3–46, 3–42, 3–48, 10–14, 10–241; 
highest yield: 3–22, 5–11, A-10, A-12, 5–21, 1–9–102, 1–6–82, 1–7–86, 15–19, 15–54, 3–42, 3–56, 3–46, 7–15, 7–36, 7–44, 7–57, 11–24, 11–26, 11–54, 10–250, 10–251.
