Abstract:

Rapeseed, one of the most efficient oil crops, occupies a pivotal position of oil supply in China. In the last 50 years, rapeseed industry experienced 3 stages of striding-development, from low yield to good quality and high yield, which played a key role in meeting the increasing edible oil demand in China. However, more than 60% of the edible oil consumption is relying on imports and the planting area and per unit area yield of rapeseed grounded to halt leading to a decreasing supply of self-sufficiency rate. The contradiction between supply and demand of edible oil will be more outstanding. Therefore, it is necessary to summarize the historical experience to draw up a strategy for rapeseed industry by relying on science and technology, which will enable China to go a step further in edible oil production.
