The purpose of the study: to analyze, describe the existing and create a new source material with the specified parameters. Develop a rapeseed variety model. The main research methods: measuring and weighing, calculation and comparison, statistical, variance and regression - to determine the reliability of the results of experiments. Methods of biochemical analysis: infrared spectroscopy and gas chromatography. The main results of the work. Among the breeding material of winter and spring rape at the initial stages of selection (collection, hybrids, breeding nursery) isolated and created valuable new source material and analyzed it for morphological and economically valuable features, oil content and fatty acid composition. The analysis of valuable collection and selection samples was carried out and characterized by important economic and valuable features of spring rape (varieties that exceeded the standard in terms of the set of indicators): ) of which 1 sample had a high oil content (45.4%), protein content of 20% and low content of erucic acid (0.42%) and glucosinolates in seeds (5.5 g / μmol) at the level of "00 "varieties. Among the samples of winter rape "00" high-yielding varieties were directly selected in all categories of nurseries in breeding nurseries: 2%, protein 22-23%, erucic acid from 0.23% to 0.32%, glucosinolates in meal from 15.0 μmol / g to 20.0 μmol / g. Samples of winter rapeseed were selected in PSV, which had a yield above the standard at the level of 1.55 - 3.05 t / ha, high oil content from 46.9% to 51.4%, protein from 22% to 23%, erucic acid content from 0.21% to 0.38%, glucosinolates in meal from 12.0 μmol / g to 16.0 μmol / g, weight of 1000 seeds - 4.5-5.0 g and high winter hardiness.
