摘要：The article deals with the effectiveness of the cultivation of new hybrids of spring rape by Rapool company selection in the conditions of the Krasnoyarsk forest-steppe. In modern agriculture the role of different kinds is increasing, the attention is paid to such indicators as a high level of adaptability, resistance to diseases, the stability of oilseed production, and the improvement in the fatty-acid composition of marketable seeds. Six new spring rape hybrids of the Rapool company selection were studied, the biological and actual crop yields were assessed, and the effects of crop structure elements on yields were determined. The assessment of the biological crop yield of the main alimony of the crop structure shows that it varies by hybrids and varies greatly from 8.8 t / ha for the Currie KL hybrid to 13.8 tons for the Miracle hybrid. The correlation analysis of the obtained data showed a significantly high correlation of yield with a mass of 1000 grains (correlation coefficient +0.86) and a high negative correlation of yield with the number of seeds in the pod and the number of fruits per plant (-0.89). The highest seed yield of 6.25 t / ha in 2018 formed a Cultus hybrid. A high economic effect was shown by the applied technology of complex protection of spring rape: the increase in production profitability of the Cultus KL hybrid was 31%, and that of the Curry KL - 14% compared with the control variant without the use of protective equipment and growth-promoting products.
