中文摘要：

作为重要的脂溶性天然抗氧化剂,维生素E的存在对预防油脂多不饱和脂肪酸过氧化、增强油脂营养品质具有重大意义。近十年来,随着人们对高等植物维生素E生物合成途径认识的不断深入,油料作物种子油脂中维生素E品质的多元化改良成为可能。本研究首先简要介绍了天然维生素E的类型和生物合成途径,然后概述了油料作物种子中维生素E和脂肪酸之间相互关系的研究进展以及油料作物种子维生素E品质改良的分子育种研究进展,最后展望了油料作物种子油脂脂肪酸和维生素E综合品质改良育种的前景。

英文摘要：

Tocochromanols （Vitamin E） are important natural fat-soluble antioxidants and dietary nutrients in seed oils, protecting the polyunsaturated fatty acids from lipid peroxidation. In the past decade, along with tremendous progresses in the understandings of the mechanisms of vitamin E biosynthesis, the manipulations of Vitamin E qualities in oilseeds were remarkable. In this review, the components and biosynthetic pathway of Vitamin E were briefly described. The relationships between vitamin E and fatty acid components in oilseeds and the molecular breeding progresses in the modification of oilseeds with desired vitamin E qualitative traits were summarized. Finally, attempts targeting on the integrated qualitative traits breeding with desired fatty acid composition and vitamin E components were proposed.
