９０年代以来，我国转Ｂｔ基因棉育种技术取得重大进展，基因转育主要采用农秆菌介导法、花粉管通道和常规转育技术，并综合运用分子杂交、室内鉴定、网室鉴定和田间自然感虫鉴定等监测手段，杂种后代处理依据转育方式确定。抗虫棉在５个方面获得了改良，在试验示范中取得显著的社会经济效益。转Ｂｔ基因棉的培育和应用，标志着我国棉花育种上升到新的水平。
Since the 1990s, great progress has been made in transgenic cotton breeding technology in China. The main methods of gene transfer are Agrobacterium -mediated method, pollen tube channels and conventional transplanting techniques. Molecular hybridization, laboratory identification, laboratory identification and field identification Natural insects identification monitoring methods, hybrid offspring treatment based on transfer method to determine. Insect-resistant cotton has been improved in five aspects and achieved remarkable social and economic benefits in the pilot demonstration. The breeding and application of transgenic Bt cotton have marked the rise of China’s cotton breeding to a new level.
