IMPROVED METHODS OF CREATING RENEWED SEEDS OF FLAX IN PRIMARY SEED PRODUCTION

Abstract

The results of scientific research are presented, which allowed to develop more efficient ways of creat-ing and multiplying seeds of flax in primary seed production. The effectiveness of an improved method for creating renewed seeds, based on the repeated reproduction of seed material obtained in the selection process of typical plants, is shown. Studies have shown that this method ensures the preservation of the required level of sowing and varietal quality of the original material. According to the ground control data, the coefficient of variation in plant height was 2.0–3.0%, and the fiber content in the stem was 4.0–4.2%, which indicates a high level of varietal homogeneity of the created seed lots. The highest efficiency of the improved method of creating flax seed was achieved when it was combined with a narrow-row, method of sowing flax (distance of 6.25 cm), which, compared to wide-row sowing (distance of 22.5 cm), increased the yield of seed material by 1.2 t / ha, or 11.1%. It was found that the yield of reproducible original material obtained using the new method in subsequent stages of primary seed production is in-creased 4.6 times compared with the adopted analogue, which indicates the high efficiency of creating original flax seeds.
