以转基因抗除草剂油菜Q3为花粉供体材料,油菜远缘杂草为花粉受体材料,在自然传粉和人工辅助授粉条件下研究甘蓝型油菜与十字花科杂草间的基因漂移频率。结果表明,以转基因油菜为父本,十字花科杂草荠菜、碎米荠、播娘蒿、诸葛菜、风花菜、遏蓝菜和菜为母本,杂交高度不亲和,基因漂移率为0 % ,无生态风险,但对野芥菜的基因漂移率高达0 .885 %。野芥菜是我国大部分地区的常见杂草,种类繁多,分布范围广,大面积种植转基因抗除草剂油菜对野生芥菜的基因污染应引起高度重视。
The transgenic herbicide rapeseed Q3 was pollen donor material. The weed was the pollen receptor material. The frequency of gene drift between Brassica napus and cruciferous weed was studied under the conditions of natural pollination and artificial pollination. The results showed that the transgenic hybrids were the parents of cruciferous weeds, shepherd’s purse, chestnuts, Artemisia annua, rhizome, cauliflower, spinach and water spinach. The hybrids were highly incompatible and their gene drift rate 0%, no ecological risk, but wild mustard gene drift rate as high as 0.885%. Wild weed mustard is a common weed in most parts of our country. It has a wide range of distribution and a wide range of distribution. It is of great importance to genetically-contaminate wild mustard in a large area of transgenic herbicide resistant rapeseed.
