Structural and correlation analyzes of the best selection numbers compared to the Demerka standard were carried out. A high positive dependence of the yield (g/m2) of seeds on the number of pods per plant (0.81) and the density of plants at the time of harvesting (0.69) and an average on the number of seeds per pod (0.38) was found. Three selection lines reliably exceeded the average experiment «(437 g/m2) in terms of productivity »: 5 (+23 g/m2), 9 (+36 g/m2) and 19 (+29 g/m2). The erucic acid content of winter rapeseed oil averaged 56.59% in the 2022-2024 experiment. Only three lines 4, 5 and 9 reliably exceeded this value. Lines 1, 18, 19/2, 21, 22 and 24 were included in the II group. The Demerk standard variety (52.85%) reliably exceeded all selection lines in terms of erucic acid content. According to the results of the studies, the three best selection lines with erucic acid content of 58.58–59.56 % were identified in terms of economically valuable characteristics. The obtained material is suitable for creating new varieties of rapeseed in the winter technical direction of use. Prepared scientific report (final). Product Description popup.authors Volodymyr Н.
