Summary. The application of oil flax seeds in various industrial spheres requires varieties with a specific biochemical composition. To select new initial material it was evaluated oil content of 4000 samples and lines of flax from the collection of N.I. Vavilov All-Russian Institute of Plant Genetic Resources during the period from 1980 to 2015. It was also evaluated protein content and fatty acid composition of 400 of them. It was revealed wide range of variability of content of protein (11.2–25.3 %), oil (33.6–52.0 %), oleic acid (8.3–37.9 %), linoleic acid (7.7–40.3 % – low linoleic acids; 65.8–68.9 % – high linoleic acids) and linolenic acid (2.8–5.0 % – low linolenic acids; 30.5–73.1% – high linolenic acids) in seeds. It was selected the sources of such valuable traits as high protein content (K-8391, Portugal; Russian varieties Smolensky (K-6977), Yubilejny (K-7785), Aleksim (K-7801), Krom (K-7887), Rusich (K-7962), Tomsky-17 (K-8002)); high oil content (Nebesny (K-7823) and Severny (K-8156) varieties); high content of oleic acid (B-9 (K-7613, Lithuania); KLV-8-198 (K-8407, Russia), and lines Gk-79, Russia, and Gk-119, India); low content of linoleic acid (B-9 (K-7613, Lithuania)) and high content of linoleic acid (lines from Linola (I-595808, Canada), Eyre (I-601679, Australia), Walaga (I-601680, Australia) varieties); low content of linolenic acid (varieties Istok (K-8677), Amon (K-8605, Czech Republic) etc.), and high content of linolenic acid (lines from the Czech varieties Mermilloid (Gk-136) and Modzuron (Gk-137)). Rucheek variety (K-7964) has a rare average content of linolenic acid (13.4 %) and an optimal ratio of omega-6 / omega-3 fatty acids for the diet feed. By CAPS markers method it was established that the low linolenic lines from the collection of N.I. Vavilov All-Russian Institute of Plant Genetic Resources contained allele of LuFAD3B gene, which had not been identical to solin 593-708 line described in the literature. This indicated to the prospects of the search for the unknown alleles of genes controlling the biosynthesis of fatty acids of flax to construct new genotypes with an altered composition of oil.
Keywords: oil flax, breeding, protein content, oil content, fatty acid composition of oil.
