本文件描述了通过群体测试策略评估一批转基因（GM）种子/谷物含量的一般要求、程序和性能标准，该策略包括对亚取样群体进行定性分析，然后对结果进行统计评估。 本文件适用于以百分比种子/谷物为基础估算转基因含量的群体测试策略，以进行纯度估算，按照给定的拒收/验收标准进行测试，以及种子/谷物批次进行堆叠事件的情况。 本文件不适用于加工产品。 注:参考文献[1]、[7]、[8]、[18]、[19]和[20]中对分组测试策略的使用进行了说明。

This document describes general requirements, procedures and performance criteria for evaluating the content of genetically modified (GM) seeds/grains in a lot by a group testing strategy that includes qualitative analysis of sub-sampled groups followed by statistical evaluation of the results. This document is applicable to group testing strategy estimating the GM content on a percentage seed/grain basis for purity estimation, testing towards a given reject/accept criterion and for cases where seed/grain lots are carrying stacked events. This document is not applicable to processed products. NOTE？Description of the use of group testing strategy are available in References [1], [7], [8], [18], [19] and [20].
