Abstract:

Transgene flows potential risk on environment and food is one of the hot spots that major public concerned. The data and information on tansgene flow in major corps published internationally until 2010 have been surveyed and analyzed. The distances of transgene flow at certain threshold level for different major crops are particularly defined. In this article, the background, aim and general consideration for this survey were discussed. On the scientific basis, the principle of classification management and threshold management are proposed to control the risk of transgene flow.

Key words: major crops, frequency and distance of transgene flow, threshold level

摘要：

转基因飘流及其可能引起的环境和食品潜在风险是公众关注的热点之一。对2010年前主要农作物转基因飘流的数据和信息进行了调研与分析,特别是对一定允许阈值下的基因飘流距离进行了归纳。在分别报道各种作物的基因飘流数据前,对调研的背景、目的及所考虑的问题进行了讨论,基于科学分析,建议采用分类管理和阈值管理的原则来控制转基因飘流的风险。
