    Identification of resistance genes to Fusarium wilt in oil flax samples with different fatty acid composition by T. A. Rozhmina, A. V. Myasnikova

    Published 2023-12-01
    “…Using a phytopathological test from the world gene pool of the species Linum usitatissimum L. 10 promising oil flax genotypes were identified – No. 3829, Uralsky (Russia), l. 6 AGT 1538, l. 12 AGT 987 (Czech Republic), Altess, Eole (France), Selectiong 3 (China), Arnu, Bison (USA) and Linda (Canada), which have effective resistance genes to the fungus F. oxysporum f. lini, differing in the fatty acid composition of the oil. Using the method of hybridological analysis, it has been established that resistance to Fusarium wilt in the low linolenic line l. 12 AGT 987 (Czech Republic) is determined by the Fu 11 gene, while in the high linolenic l. 3 Altess (France) it is Fu 4 (χ2 = 0.02…2.89). …”
