新技术的发展使油料作物各种品质遗传改良成为可能。目前油菜产业面临的挑战是平衡各种脂肪酸水平，使其构成适应商业需要。在国际市场上，亚麻、向日葵和大豆等油料作物是油菜的竞争者，使得改良油菜品质迫在眉捷。北美产品登记管理要求将脂肪酸的饱和程度降至7％以下，以获得低饱和脂肪酸的油菜商标，这将为扩大油菜的市场份额起重要作用。油菜品质改良的另一方面要求源于营养考虑，它要求一种和多种不饱和脂肪酸达到人类需求的水平。为适应各种不同需求，油菜品质育种应针对不同用途发展不同脂肪酸类型的油菜品种。
The development of new technologies makes it possible to genetically improve the quality of oilseed crops. The challenge now facing the rape industry is to balance the levels of various fatty acids and make them suitable for business needs. In the international market, oilseeds such as flax, sunflower and soybeans are rapeseed competitors, making the improvement of quality of rapeseed. North American product registrations require that the degree of saturation of fatty acids be reduced below 7% in order to obtain a rapeseed trademark of low-saturated fatty acids, which will play an important role in expanding the market share of rapeseed. On the other hand, the improvement of rapeseed quality is due to nutritional considerations, which require that one or more types of unsaturated fatty acids meet human needs. In order to meet different needs, rapeseed breeding should be for different purposes to develop different types of rapeseed fatty acids.
