The object of research is the parent components, hybrids of winter rape. The obtained results: The morphological features and biochemical parameters of 46 sterile analogues of maternal lines of winter rape hybrids and similar indicators of maternal lines of sterility fixers of winter rape hybrids are analyzed. Work continued on the creation of new maternal lines. Morphological features and biochemical parameters of fertility-restoring lines of winter rape hybrids are analyzed. The minimum content of glucosinolates is 12.5 μmol / g, oil content up to 46.2%. The dynamics of flowering of potential parental components is determined to determine the pairs that coincide on this basis. A promising commercial hybrid of winter rape Vegas for food use with a potential yield of 4.6 t / ha and an oil content of 45% has been created and submitted for the State Variety Testing. The maternal form is the K1FOA09 line, with an oil content of 45%, the parent form is the RRF line. The level of heterosis is 20%. A method of laying hybridization plots (obtaining F1 seeds) of winter rape has been developed, which provides the maximum yield of conditioned seeds. Practical value of the results: Helps increase the productivity of rapeseed in the production area by 15-20%, or 0.3-0.5 t / ha. The use of a hybrid will optimize the use of material and technical resources in the cultivation of rapeseed. Key words: fertility restoration, hybrids, economically valuable traits, rapeseed, self-pollinated lines, breeding, sterile lines, cytoplasmic male sterility.
