ASSESSMENT OF LINEN FLAX VARIETIES OF NATIONAL AND FOREIGN SELECTION ACCORDING TO THE OUTPUT OF FIBRE FROM FLAX TRUST IN INDUSTRIAL CONDITIONS

Abstract

The research explores the linen flax varieties of domestic selection. These varieties are seen to be promising from the standpoint of fibre output obtained when processing flax trust in industrial conditions at the flax processing enterprises. The linen flax varieties were compared with the varieties of the foreign selection cultivatedRussia. The authors compared technological value of flax trust of domestic and foreign selection on the basis of “total fiber yield” when dividing flax trust into two groups of quality: low-quality (number 0,50-0,75) and high-quality (number 1,00 and more). There was no evident advantage observed. The detailed analysis (complete assessment scale of flax trust quality) and assessment of varieties indicate that domestic varieties are characterized by higher fiber output (average index is 14.7) than foreign varieties (average index is 16.7). The paper estimates the capacities potential of domestic and foreign selections for fiber output when processing flax trust in industrial conditions. The authors outline the highest and lowest parameters of fibre output produced from the flax trust of low quality and high quality have been identified. The most promising varieties are seen as follows: Universal, Alexandrite, Alexim, Tomskiy 18, Tomskiy 17, Lenok, Smolich of domestic selection (the capacities potential is 76,9 - 88,7%). The authors observed 87.3% -98.0% capacities potential for fiber output from flax trust of higher quality in the following varieties: Tomskiy 18, Tomskiy 17, Alexandrite, Tost, Universal, Diplomat of domestic selection and Pralesk of foreign selection. The authors found out that flax-fibre of domestic selection is the most efficient for flax trust output in the industrial conditions.
