Productivity of spring rape hybrids according to the Clearfield ® system: comparative analysis using multivariate statistics

The productivity of the new generation of Rapool hybrids suitable for cultivation according to the Clearfield ® system has been established. As a result of the research, it was found that the germination of spring rape varied depending on the hybrid. Rape plants were characterized by the most powerful habitus by the X-XI stage of organogenesis. At the same time, the maximum biomass was formed by the hybrid Cyclus KL-7800 g. At the same time, the height of the Chip hybrid plants was the maximum-147 cm, with a leafage of 10 pcs./plant. The early-maturing hybrid Chip KL provided the maximum yield among the studied hybrids - 4.43 t / ha. The second result in terms of yield was shown by the Cyclus KL hybrid - 4.07 t / ha. The hybrids Cebra CL and Cultus CL showed the third result among the studied hybrids. The Cyclus CL hybrid provided the maximum oil content - 47.8%, which is 0.9-3.2% more in comparison with other studied hybrids. However, the maximum oil collection was provided by the hybrid Chip KL - 2064.4 l/ha. The hybrids Cultus CL, Cebra CL and Cyclus CL provided the oil harvest of 1822-1945.5 l / ha, respectively. Statistical regularity shows that, on average, in the array of studied rapeseed hybrids, an increase in yield per t/ha corresponds to an increase in oil harvest of 505 kg / ha.
