TECHNOLOGICAL VALUE OF MODERN FLAX VARIETIES OF DOMESTIC AND FOREIGN SELECTION ON THE OUTPUT OF FIBER FROM FLAX

The article presents the results of studies on the identification of competitive flax varieties of domestic selection for fiber output in the processing of flax under production conditions at flax processing enter-prises in comparison with the varieties of foreign selection cultivated in the Russian Federation. A com-parative analysis is carried out of flax technological value of domestic and foreign selection on the basis of ``total fiber yield`` when dividing flax into two groups according to quality: low quality (numbers 0.50 – 0.75) and high quality (number 1,00 or more). With this division, there is no clear advantage of the compared set of the two groups. A more detailed differentiated analysis (across the entire quality scale of flax seed) with a rating of varieties showed that domestic varieties are characterized by a higher fiber yield (average index 14,7) than foreign ones (average index 16,7). The degree of realization of the poten-tial opportunities which inherent in the varieties, both domestic and foreign selection for the fiber yield in the processing of flax under industrial conditions. The best and worst varieties are assessed to unleash the potential for the release of fiber from low – quality and high – quality flax. The best varieties include: (low – quality flax) Universal, Alexandrite, Alexim, Tomsky -18, Tomsky-17, Lenok, Smolich of domestic selection (the potential manifests itself at 76,9 – 88,7%). At 87,3 – 98,0 the potential for the yield of fiber from higher quality flax seed is realized in the varieties Tomsky -18, Tomsky-17, Alexandrite, Toast, Uni-versal, Diplomat of domestic selection and the variety of foreign selection Praleska.
