从棉花种植、供试棉株器官选择、棉铃虫饲养、标准试虫选择、室内生测方法、抗性级别评价标准等方面 ,系统地总结了转 Bt基因棉抗虫性的室内鉴定技术。以从美国引进的转 Bt基因棉“保铃棉 32 B”为参考 ,对我国自行培育的第一个转 Bt基因棉“品种国抗棉 1号”的抗虫性进行了较系统的比较鉴定。
The indoor identification techniques for insect resistance of transgenic Bt cotton were systematically summarized in terms of cotton planting, organ selection for cotton plants, breeding of cotton bollworm, selection of standard insects, indoor bioassay methods and evaluation standards of resistance level. Taking the transgenic Bt cotton “B32B” introduced from the United States as reference, the insect resistance of the first transgenic Bt cotton “Guomingmian 1” cultivated in our country was systematically comparatively identified .
