Flax fiber is used to make textiles, paper and other products. These products are environmentally friendly, so these products are very popular among consumers. In Ukraine, there is no regulatory frame work governing the quality of oilseed flax. The article scientifically substantiates the influence of qualitative parameters of oilseed flax straw, namely: average length of stems, diameter and weight of stems on the yield of bast, as well as parameters of oilseed flax retted straw – average length of stems, diameter and weight of stems on fiber yield, which are important in expediency of industrial processing of this bast material. This was done using correlation analysis, a method of three-factor mathematical planning of an experiment using the software product MathCAD 14. The obtained correlation coefficients and three-factor analysis confirmed the importance the yield of bast and the yield of fiber and their direct relationship with the length, diameter and weight of stems. Mathematical modeling and calculations of the influence of oilseed flax straw and retted straw obtained experimentally, on the yield of bast and yield of fiber confirmed the theoretically substantiated hypothesis, which is as follows: the main quality characteristics of oilseed flax straw and retted straw as industrial raw material, littering, straw color group (fiber color group), as well as separability – for retted straw. Secondary importance for straw and retted straw of oilseed flax are technical and total length, diameter, technical part in the total length of the stem, because they are reflected in the values of yield bast and yield fiber.
