近几年来 ,转基因抗虫棉在各棉区的种植越来越广泛 ,为了验证其抗虫效果 ,我们采用转基因抗虫棉与常规棉对比试验的办法 ,对其抗虫性进行了观察鉴定 ,现将试验结果报告如下。1 材料和方法1 .1 试验材料转基因抗虫棉“33Ｂ”、豫棉 1 6号 (均为市售种子 )。1 .2 试验基本情况
In recent years, the transgenic cotton has been planted more and more widely in each cotton area. In order to verify its insect-resistance effect, we compared the insect resistance of the transgenic cotton with that of the conventional cotton. The test results are reported below. 1 Materials and methods 1.1 Test material Transgenic insect-resistant cotton “33B” Yu-cotton No. 16 (all commercially available seeds). 1 .2 test the basic situation
