| 摘 要： | 1997～1998年通过接幼虫和即将孵化的卵，进行转Bt基因棉室内鉴定技术及表示方法研究。结果表明，以接即将孵化的卵粒，4d后观测其取食情况最为简便准确，根据试验结果拟定检测分级标准，提出利用抗虫指数计算各抗虫棉群体抗性，依此可以量化地表示转Bt基因棉的抗虫性。

| Abstract: | The identification technique and classification method of Bt transgenic cotton for resistance to cotton bollworm(CBW)were studied by putting hatching CBW eggs on cotton leaves indoors. The result showed that it was easier and more accurate to put hatching eggs on leaves and observe its feeding 4 days later. According to the experimental result, the classification standard was made. It was put forword that the population resistance of each Bt transgenic cotton could be caculated by pest-resistant index. In this way, the resistance of Bt transganic cotton to CBW could be completely and quantitatively expressed. |
