抗虫棉,是通过现代生物技术与常规育种相结合,将外源抗虫基因导入棉花植株而培育出的棉花新品种。抗虫棉有形态抗虫棉、生理生化抗虫棉和转基因抗虫棉之分。目前生产中推广的抗虫棉大都是转Bt基因,转基因抗虫棉品种类型较多,在适应性、长势和抗逆性等方面各具特色,可以满足不同
Bt cotton, through the combination of modern biotechnology and conventional breeding, the introduction of foreign insect-resistant genes into cotton plants and breeding of new varieties of cotton. Insect-resistant cotton has morphological insect-resistant cotton, physiological and biochemical insect-resistant cotton and transgenic cotton insect points. At present, most of the insect-resistant cottons popularized in production are transgenic Bt genes. There are many types of transgenic insect-resistant cotton varieties, which have their own characteristics in terms of adaptability, growth and stress resistance so as to meet different needs
