The results of breeding evaluation of parent forms and hybrid offspring of strawberry on resistance to white spot have been presented in the article. The genetic sources of this trait, the varieties Kupchikha, Lyubava, Tsaritsa, Bereginya, Venta and selections of 2-299-4, ISP-5(K), 3-5-1 have been singled out. The perspective families in breeding for increased resistance to this pathogen are Kupchikha x Krasnyi Bereg, Kupchikha x Lyubava, Kupchikha x Honei, 2-299-4 x Tsaritsa, ISP- 5 (K) x Kent, Tsaritsa x Darselect, Maryshka x 3-5-1, 3-5-1 x Red gontlit, 808-28 x Tsaritsa and populations from the combined pollination varieties Kupchikha, Tsaritsa, Venta. It was established that the dominance of resistance to white spot in F1 is possible when crossing between themselves resistant and relatively resistant genotypes. |
