摘　　要：田间生殖隔离状态下,将野生大豆和栽培大豆种植在抗草甘膦转基因大豆周围,按固定距离收获。每年对一部分实施喷施高剂量草甘膦进行鉴定筛查,另一部分收获留待下年继续鉴定筛查。对每年连续筛查中存活植株提取DNA,进行对目的基因CP4-EPSPS的PCR检测,结果为阴性。初步判断在监测的三年时间内没有发现抗草甘膦转基因大豆通过风媒介使花粉传播,对田间大豆及其近缘种野生大豆产生明显的基因漂移。In reproductive isolation the experiment planted wild soybean and cultivate soybean around Roundup Ready Soybean and harvested soybean according to fixture distance, A part of soybean was inspected with high dosage glyphosate, remaining soybean was harvested and kept on inspecting the next year. Distilled DNA from the survival soybean which maybe resist to glyphosate and inspected CP, --EPSPS with PCR, the result was negative. The survey showed that RRS did not transfer pollen to cultivate soybean and wild soybean by anemophily in the inspected three years.
