COMPETITIVENESS OF DOMESTIC VARIETIES OF FIBER FLAX IN TERMS OF YIELD AND QUALITY OF LONG FIBER WHEN PROCESSING FLAX UNDER MODERN PRODUCTION CONDITIONS

Comparative data on the quantity (yield) and quality (number) of long fiber obtained from flax of fiber flax varieties of foreign and domestic origin are presented during control developments using traditional technology at flax processing enterprises of the Russian Federation. A rating assessment of varieties according to these characteristics for flax trees of low (numbers 0.50–0.75) and higher quality (numbers 1.00 and higher) was carried out according to the existing gradation of division of flax trees into two qualitative groups. It was found that varieties of domestic origin, both in terms of long fiber yield (average index 14.6) and number (average index 15.6) from low-quality flax stands, are inferior to foreign varieties with average indexes of 12.2 and 11.8, respectively. Long fiber obtained from high-quality flax straw of domestic varieties is characterized by a high yield (average index 13.9) and better quality (average index 14.6). For foreign varieties, the average index is: for long fiber yield - 18.0, for number - 16.0. In order to determine the extent to which the potentialities inherent in the varieties in terms of the yield of long fiber are realized in production practice, a comparative analysis was carried out. The results are revealed by means of state test data and the results of control developments. An extremely low degree of implementation was noted. For the best varieties it is slightly more than 50%. A large yield of long fiber under production conditions was obtained from highquality flax trees of domestic breeding varieties, such as Alfa, Aleksim, Lenok, Tost, Sursky and Alexandrite.
