摘　　要：对国内外传统和新型授粉控制系统的特点及发展潜力进行全面评述,为油菜杂种优势利用提供参考。中国杂交油菜生产的授粉控制系统具有多元化的特色,包括自交不亲和、细胞质雄性不育、细胞核雄性不育、化学杀雄和双重雄性不育等途径。由于目前油菜生产水平提高,许多遗传改良的新种质要尽快投入应用,加之国外改良Ogu CMS和基因工程雄性不育研究的快速发展,虽然通过组合我国现有的不同授粉控制系统可以增强稳定性,对于促进杂交种生产具有一定潜力,但开发我国具有自主知识产权的新型高效授粉控制系统,是目前亟待解决的首要问题。In order to provide a comprehensive reference for hybrid rapeseed production in China,the characterizations and the potentials of different traditional and new pollination-control systems are summarized in this paper.Diversifying pollination-control systems are used in commercial hybrid production in China,including self-incompatibility,cytoplasmc male sterility,genic male sterility,and chemical gametocide etc.Owing to the fast increase of rapeseed production,more and more genetic-improved germplasms need to be put into hybrid production.Ogura CMS and genetic-engineering male sterility have made great success in Europe and North America.Under this circumstance,rapeseed industry in China needs some more effective pollination-control systems for higher level hybrid production.Constructing of some combing systems with different pollination-control systems can enhance the stability and promote hybrid production.
