为建立国家转双价双Bt抗虫基因棉环境安全评价技术，对转双价双Bt基因（Cry1Ac＋Cry2Ab）抗虫棉栽培地生存竞争能力进行研究，结果表明，转双价双Bt基因棉花与对照赣棉11相比，各生育期株高生长具有显著竞争优势，优势值3.48～4.75 cm；吐絮期棉覆盖度竞争优势超对照46.77个百分点，达显著水平；产量竞争力优势籽棉超对照1 013.85 kg/hm2，皮棉超对照433.20 kg/hm2，均未达到显著水平；发芽率竞争优势极显著，超过对照2.75个百分点。与非转基因常规棉相比，转双价双Bt抗虫基因棉生存竞争能力优势显著。

The research studied for establishing the environmental safety assessment technologies of bivalent Bt genes （CrylAc＋Cry2Ab） transferred cotton in China. The result showed that ：the plant height competitive advantage of transgenic cotton harboring double gcnes（CrylA c＋Cry2A b ） increased 3.3,8-4.75 cm in whole growth stages compared to the non- transgenie cotton significantly.The coverage competitive advantage was 46.77 pencentage points more than control significantly.The yield competitive advantage of seed cotton was 1 013.85 kg/hm2 more than control and the lint yield was 433.20 kg/hmz more than control ,but not significantly.The germination rate competitive advantage was 2.75 percentage points more than control, but the difference was not significant. The survival competitive ability of transgenic cotton harboring CrylAc ＋Cry2A b double Bt genes was higher than the non-transgenic cotton significantly.
