Initial material for breeding of fiber flax under conditions of the Volga-Vyatka region

Resumo

Sixty two cultivar samples of fiber flax of various ecological-and-geographic origin were studied for basic economically valuable traits (straw and seed productivity, fiber content and its quality) in 2014–2016 under conditions of the Volga-Vyatka region (Kirov oblast). The best genotypes were identified in terms of a set of traits: Flax of Heilonjiang no. 7 and no. 10; Heiya 11, 13 and 14; Huanguang 2 (China); Belinka (the Netherlands); and AP₅ (Russia). Straw yield depends on the stem technical length (r = 0.71–0.76). Cultivar samples having high fiber contents (28.7–34.5%) are identified: Mirazh, Tverskoi, AP₅, AP₆, Pskovskii-93, Dobrynya, Nord, Peresvet (Russia), B-179 (Lithuania), and Merilin (the Netherlands). High fiber durability is characteristic of samples Soglasie (Belarus)—20.3 kgf; Er-27 (Russia)—18.5 kgf; and B-179 (Lithuania)— 17.8 kgf.
