Create heterosis hybrids and investigate their technological characteristics. Sterile CMS lines and fertility-restoring lines of various origins will be used as sources of heterosis hybrids. The morphological and biochemical parameters of the parent components, as well as their influence on the economically valuable traits of hybrids will be studied. The combinatorial ability of the parental lines will be studied by obtaining test hybrids. Experimental hybrids will be studied according to the scheme of State Variety Testing. popup.description2 The material for the research is the parental components of winter rapeseed hybrids (sterile analogues of maternal lines of IOK selection and their sterility fixers and fertility-restorer lines), experimental F1 hybrids of winter rapeseed. Promising parental components of winter rapeseed hybrids with high combining ability were identified based on the results of determining the morphological and biochemical indicators of parental components and F1 hybrids created with their participation. Based on the results of evaluating the economically valuable indicators of sterile analogues of BC5 generation lines and their sterility fixers, 108 maternal lines of winter rapeseed hybrids of IOK selection were identified, promising in terms of elements of the crop structure and indicators of oil content and quality. A high degree of similarity of self-pollinated maternal lines of winter rapeseed hybrids and their sterile analogues was established. The best lines of pollen fertility restorers of IOK selection, suitable for creating F1 hybrids for food use, were selected based on the results of studying morphological and biochemical indicators, and evaluating the timing and rate of flowering. The influence of biochemical indicators of 15 sterile lines and 9 lines of fertility restorers on the formation of relevant traits in F1 hybrids of winter rapeseed created with their participation was determined. The genotypes that provided increased oil content and low glucosinolate content in hybrids were determined Product Description popup.authors Kalinova Mariya G Senyk Ruslana V. Taranets Tatiana O.
