| 摘 要： | 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。

| Abstract: | Eight common Chinese cruciferous weeds were grown in pairs with the glyphosate-tolerant GM rapeseed variety Q3. The frequency of gene flow from the herbicide-tolerant GM rapeseed to these cruciferous weeds was studied under either natural or manual pollination conditions. This study is to provide scientific evidence for the evaluation of the ecological safety of growing herbicide-tolerant GM rapeseed. Firstly, we studied the gene flow from glyphosate-tolerant GM rapeseed to cruciferous weeds under natural... |
