Abstract

Cultivation of fiber flax and oil flax in Kurgan region is of current interest due to the presence of flax seed and straw processing enterprise – SUE Len Zauralya, Kurgan. To increase the production of highquality flaxseed oil and flax products, the level of flax production should be increased via theoretically substantiated cultivation technologies. Propagating a new variety, plant breeders consider the needs of two categories of consumers – flax producers and flax processors. Some of them need fiber flax varieties of high yield (seed and fiber) and high fiber quality resistant to diseases and lodging, adapted to conditions of Trans-Urals and Siberia. Other consumers need fiber flax varieties that meet numerous requirements of textile, construction, automotive, aviation, medical, and other sectors of the economy, and are suitable for processing by state-of-the-art flax processing equipment. The approach to develop a variety has currently become targeted and customized. Varieties grown in the study area and used as a standard showed high fiber yields: Tomsky 17 – 0.68 t/ha, Tomsky 18 – 0.69 t/ha. The results of the three-year study showed high yields of new varieties: Tost 3 – 0.98 t/ha, Tost 4 – 0.86 t/ha, Tost 5 – 0.82 t/ha. The fiber yield of these varieties was also high: Tost 3 – 0.71 t/ha, Tost 4 – 0.68 t/ha, Tost 5 – 0.66 t/ha.
