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 rapeseed at the initial stages of selection (collection, hybrids, breeding nursery), valuable new raw material was selected and created, and its analysis was carried out according to morphological and economically valuable characteristics, oil content and fatty acid composition. Valuable collection and selection samples were analyzed and characterized according to important economic and valuable traits of spring rapeseed (specimens that exceeded the standard in terms of a set of indicators. Indicators of inheritance of economic and valuable traits in hybrids of the first generation were established. In CSR of spring rapeseed, 5 cultivar samples exceeded the standard.1 valuable variety sample was selected, in which the oil content was 45.0%, with a yield of 3.45 t/ha, and the weight of 1000 seeds was 7.1 g. In PSV, selection numbers PSV12/20, PSV13/20 and PSV18/ provided the highest yield 20 - 3.50 t/ha. The mass of 1,000 seeds of the studied selection numbers varied from 4.0 g to 5.3 g. In the Kyrgyz Republic, 15 variety samples were selected and studied, among them 9 numbers were selected (table 5), which in terms of a complex of economic and valuable characteristics and seed yield significantly exceeded the standard , the yield of which was (Magnat variety) - 2.4 t/ha. In the collection nursery of winter rapeseed, samples were selected according to the fatty acid composition of the oil for their further. Product Description popup.authors Kondratiuk Viktor V.
