SNP芯片在油菜分子育种的应用

油菜是我国最主要的油料作物之一, 肩负着国内植物油供给的重任,所产菜油占国产油料作物产油的57%以上。近年来,中国面临严重的食用油供给安全问题,国产植物油短缺,进口依赖度达60%以上。我国的油菜产量低、生产成本高、市场竞争力相对较弱是制约我国油菜生产的主要原因之一。努力提高我国油菜育种水平是促进油菜产业发展、保障我国食用油供给安全的有效途径。新型高通量分子育种技术-SNP育种芯片的开发与利用为快速高效油菜育种带来了生机。在油菜及其基本种的基因组测序、SNP分子标记的开发等方面我国已具有良好的研究基础。我国油菜科技工作者正在致力于引进和建立国内自己的油菜育种SNP芯片,为提高油菜育种效率提供技术支撑。

Application Prospect of SNP Array in Rapeseed Molecular Breeding

Rapeseed is one of the primary oil crops in China,which is laden with heavy responsibility to insure the supply of plant oil.Rapeseed oil accounts for over 57% of the oil production from all oil crops in China.In recent years,China faces severe security problem of edible oil,and over 60% are depended on import.The low yield and high production cost of Chinese rapeseed varieties are the main reasons which restrict the development of rapeseed growing in China.So,strengthening the rapeseed breeding technology ...
