The representative hybrid Zhongyouza 19, breaking through the contradiction in simultaneously achieving high oil, high yield, and multiple resistance, achieved an average oil content of 50.09%. It is the first winter-type rapeseed variety with a high oil content of up to 50%, high yield, and multiple resistances, and it is suitable for mechanized harvesting. In 2020, the accumulated demonstration and extension area of Zhongyouza 19 in the Yangtze River basin, China, exceeded 200,000 ha, ranking the top three in China’s winter rapeseed promotion area. Under physical pressing, the average oil production increased by 100.6%, and the income per hectare increased by 3,649.8 RMB. It has successfully created many sets of green and efficient production patterns widely used in the Yangtze River basin, which effectively supports the overall efficiency improvement of the rapeseed industry and ensures the self-sufficiency rate of China’s edible oil.
