Cultivated common flax (Linum usitatissimum L.) is a traditional Russian technological crop of complex usage. Estimation of seasonal effects in economically valuable traits (productivity of straw and seeds; content of fiber and its quality) of long-fiber flax under conditions of Volga-Vyatka region (Kirov region) in 2014 - 2017 is presented in the article. Objects of study – 140 varieties of long-fiber flax different in ecological and geographic origin. Stable and plastic traits are selected according to correlation coefficient. Strong “genotype - environment” interactions were expressed by seed productivity, number of bolls and seed per plant; moderate interactions – by productivity of straw and fiber; weak interactions – by plant length, fiber content, 1000-grain mass. Strong correlation is pointed out between straw productivity and total and technical plant height (r = 0.71±0.09…0.78±0.08) in average for years of study. Sources are selected for most important directions of long-fiber flax breeding: for straw productivity – Sinel, Vizit (Russia). Merilin (The Netherland), Soglasie (Belarus), Heiya 11, Heiya12 (China); for seed productivity – Priboj, Sinichka, Er-27 (Russia), Ottawa (Canada), Soglasie (Belarus), Belinka, Merilin (The Netherlands); for fiber content– Mirazh, Peresvet, Tverskoj, Pskovsky-93, Dobrynya (Russia); Merilin (The Netherlands); Charivny, Zaryanka (Ukraine); for fiber durability – Soglasie (Belarus), Sinel, Pskovsky-93 (Russia), Kamenyar, Baltuchaj (Ukraine), B-179 (Lithuania); for fiber flexibility – Flax of Heilonjiang №7, Huaguang 2, Heiya 11, Heiya 13 (China); Honkei-25 (Japan), Kamenyar (Ukraine), Priboj (Russia). By a complex of economically valuable traits the following genotypes are selected: Sinel, TOST 3, Peresvet (Russia), Flax of Heilonjiang №13 and Heiya 12 (China), Merilin (The Netherlands).
