棉花抗虫新杂交材料研究

以转基因Ｂｔ抗虫棉为供体亲本，以一组高产，抗病或抗虫品种（系）为母本杂交培育了一批抗虫杂交新材料，结果证明以无蜜腺棉与Ｂｔ转基因品系杂交获得的杂交种在产量，品质和抗虫性方面表现最好，是一种理想的抗虫新材料。

STUDIES ON COTTON NEW CROSS MATERIALS RESISTANT TO INSECTS

A batch of new cross materials derived from the crosses between a Bt transgenic line used as a providing parent, and several normal lines used as maternal plant, had high yield and resistance to disease or insects. The results showed that the cross breed from the cross between a nectariless stock and the Bt transgenic line had reached the best condition in the cotton yield, quality and resistance to insects. It is a desirable new materials resistant to insects.;
