The genetic basis of the inheritance of 00-zero quality in rapeseed hybrids and cultivars will be studied, on the basis of which the selection process of breeding 00-zero cultivars will be improved and new rapeseed varieties adapted for cultivation in the Forest-Steppe, Polissya and Polissya will be created and submitted for state testing. improved system of their primary seed production. The research program is aimed at solving the main problems of selection improvement of winter and spring rape on important economic and valuable features, which is relevant in the context of increasing competition in the seed market. popup.description2 The object of research is the selection material of spring and winter rape. The purpose of the study: to analyze, describe the existing and create a new source material with the specified parameters. 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. Valuable collection winter rapeseeds were analyzed and characterized according to the fatty acid composition of the oil, and valuable and promising varieties for selection were selected. Among the combined inbred lines of spring rape, the study of number 24 - 3.54 t/ha was continued according to the complex of economic and valuable characteristics and yield; 3 samples of KSV1/20 – 3.01 t/ha, KSV9/20 – 3.21 t/ha and KSV3/20 – 2.81 t/ha were selected. Selection numbers of spring rapeseed PSV12/20, PSV13/20 and PSV18/20 were selected for preliminary variety testing; and winter rape - KS30/21, KS26/21, KS33/21, KS39/21 and KS28/21. In KSV spring rape, the highest yield was provided by selection numbers KSV1/20 – 3.01 t/ha, KSV9/20 – 3.21 t/ha and KSV3/20 – 2.81 t/ha. In KSV of winter rape - three samples were selected: KSV3/21, KSV6/21 and KSV10/21, which ensured the yield of conditioned seeds of 4.23 t/ha, 4.38 t/ha and 4.29 t/ha.
