杂草是制约大豆生产的关键因子,抗除草剂转基因大豆为大豆生产提供可持续稳产和增产的潜力。目前,我国转基因大豆至今还处于试验阶段,还不能商业化种植。2010年在中国农科院廊坊科研中试实验基地用5点取样法调查研究了抗草甘膦转基因大豆AG5601、呼交03-263、呼交06-698对豆田杂草的影响。结果表明:在对豆田杂草种类及数量、田间密度(MD)、田间均度(U)、田间频率(F)和相对多度(RA)调查中,只有抗草甘膦转基因大豆呼交03-263豆田中狗尾草的F和RA显著低于亲本受体蒙豆12,其它杂草无显著差异。这说明抗草甘膦转基因大豆AG5601、呼交03-263、呼交06-698对豆田杂草没有显著影响。
Weeds are the key factor restricting soybean production and herbicide-tolerant GM soybeans have the potential to provide sustainable, stable yields and increased yields for soybean production. At present, China’s genetically modified soybeans are still in the experimental stage, it can not be commercialized. In 2010, the impact of glyphosate-resistant transgenic soybean AG5601, call hybrid 03-263, call hybrid 06-698 on weed weeds was investigated using 5-point sampling method at Langfang Research Pilot Base of Chinese Academy of Agricultural Sciences. The results showed that only the glyphosate resistant transgenic soybean (Oryza sativa L.) Oliver 03 was investigated in the survey of weed species and quantity, field density (MD), field average (U), field frequency (F) and relative abundance (RA) -263 Forage and RA of Setaria viridis were significantly lower than that of the parental Rehmannia glutinosa 12, and no significant difference was observed for other weeds. This shows that the glyphosate-resistant transgenic soybean AG5601, call 03-663, call 06-698 weed on the weed has no significant effect.
