The main tasks of the laboratory of oil flax breeding are the implementation of works on oil flax breeding, the breeders and foundation seed growing of varieties included in the State Register, the improvement and development of efficient breeding methods. 6 experts work in the laboratory, among them are 2 PhD in agriculture, 1 PhD in biology and 3 researchers without science degree.
The breeding of oil flax in FSBSI FSC VNIIMK is being carried out from the second half of the 30s. Up to 1987 the laboratory was headed by a PhD in agriculture, M.A. Sorochinskaya, in the subsequent period and up to 2010 the laboratory was headed by a PhD in agriculture, F.M. Galkin, at present, the laboratory is headed by L.G. Ryabenko, a PhD in agriculture.
The laboratory's scope of activity includes the research on the theoretical and methodical plan for increasing the efficiency of flax breeding, as well as the practical work on breeding of new competitive flax varieties.
Over the last 20 years, as a result of breeding work in VNIIMK, 7 varieties of oil flax were developed and released, which are resistant to Fusarium blight and have high productivity and high oil content of seeds. In 2015, 24 varieties of oil flax were included in the State Register of breeding achievements approved for cultivation, among them are 12 varieties of breeding of VNIIMK and its experimental stations: VNIIMK 620, VNIIMK 630, Rucheyok, Fliz, Biryuza, Isilkylsky, Legur, Sokol, and Nebesny.
At the present stage, the main goal of oil flax breeding is the development of varieties adapted to the conditions of the North Caucasus, the Volga region, and other areas of cultivation of this crop, with a potential yield of up to 3 tons/ha, the oil content of seeds of up to 50%, with high resistance to diseases, pests, and lodging, and suitable for dual-use – for seeds and fibre.
In 2005, the laboratory of oil flax breeding of VNIIMK has developed a collection of lines with various ratio of fatty acids in the oil: from 16 to 73% of linoleic acid and from 1.6 to 56% of linolenic acid.
Flaxseed oil with linolenic acid content of 2.3-4.0 % surpasses by oxidation stability the traditional oil in 4-12 times, depending on the temperature of oxidation, thus allowing to use flaxseed oil for food purposes.
In cooperation with the laboratory of soybean genetics and immunity, research is being conducted on the flax resistance to Fusarium blight and frost. As a result, for the first in the world, flax lines of the “Y-1” series were developed, with a complete resistance to Fusarium blight and flax sickness. In the future, varieties of oil flax developed on the basis of such lines can be cultivated in short (3-4 years) crop rotations and even with monoculture. A group of frost-resistant lines of the “Snegurok” series was also developed, which in the conditions of Kuban are capable of overwintering successfully during autumn sowings and ripen in early June.
In addition to breeding, the laboratory also carries out the breeders and foundation seed growing of the developed varieties of oil flax in amounts necessary for the conduction of variety changing and renovation.
