油菜转基因育种研究进展

Advances of Transgenic Breeding on Rapeseed (Brassica napus)

简要介绍了国外油菜转基因育种情况 ,包括转除草剂抗性基因 ,病原菌抗性基因 ,耐重金属基因 ,影响种子贮藏产物基因 ,影响繁殖特性基因 ,医药和工业产品基因 ,以及启动子调节基因等。较详细介绍了湖南农业大学在Bt毒蛋白基因转化甘蓝型油菜育成抗虫新品系、基因工程雄性不育系、恢复系选育和杂种优势利用 ,以及反义FAD2基因转化甘蓝型油菜双低品种提高油酸含量的研究结果 ;浙江省农科院利用反义PEP基因转化甘蓝型油菜提高种子含油量的研究结果。

The advances abroad of gene transformation on rapeseed (Brassica napus) were introduced, including genes of tolerance to herbicides, tolerance to fungus pathogens, tolerance to viral pathogens, tolerance to heavy metal, oil component of seed, protein component of seed, secondary metabolites, reproductive characteristics,medical or industry products and regulation of promoters. It described advances of transgenic breeding of rapeseed (Brassica napus) in Oil Crops Institute, Hunan Agricultural University and Institute for Application of Atomic Energy, Zhejiang Academy of Agricultural Sciences. The paper dealt with Bt transgenic insect resistant rapeseed line, transgenic sterile line, restorer line and their hybrid, transgenic high oleic acid content rapeseed line and transgenic high oil content rapeseed lines.
