| 摘 要： | 从甘蓝型油菜的生活周期出发,概述了甘蓝型油菜及其近缘种的开花习性、甘蓝型油菜与其近缘种的杂交亲和性、杂种及其回交后代的育性和适应性,评价了在中国环境条件下甘蓝型油菜中的外源基因向其近缘种漂移而导致生态风险的可能性.认为在中国环境条件下,转基因甘蓝型油菜向其野生杂草近缘种的基因漂移风险较小,而如何防止转基因向白菜型油菜(Brassica rapa)和芥菜型油菜(B.juncea)转移应作为中国转基因甘蓝型油菜基因基因漂移风险控制的关键.

| Abstract: | This paper reviewed geographical distribution, flowering habits, hybridization compatibility, viability and fertility of hybrids, progeny and their backcross generations in China based on the life cycle of B.napus and its relative species. In view of the current research and environmental release of worldwide, the risk of gene flow between transgenic rapeseed and its relative species was generally assessed. We concluded that the possibility of gene flow from transgenic rapeseed to its wild weedy relatives was relatively low, and key to control gene flow from transgenic B.napus may be reducing the transmission probability of transgene to B.rapa and B.juncea under China environment. |
