我国对抗虫棉研究早在八十年代就开始了。初期主要在形态学和生化抗性两方面进行研究。形态学方面如:叶片光滑、无蜜腺、鸡脚叶、窄卷苞叶、红茎和红叶、多茸毛等性状,这些性状不利棉铃虫产卵和生存。第二类以生化物质为抗性的,如高棉酚、高单宁、高类萜烯含量等的群体。但效果都不太好,发展受到限制。最近几年来,随着基因工程和育种的结合,育种
Research on insect-resistant cotton in our country began in the 1980s. Initially mainly in morphology and biochemical resistance of two aspects of research. Morphology, such as: smooth leaves, non-nectary, chicken feet, narrow bracts, red stems and leaves, more hair and other traits, these unfavorable spawning instars and survival of cotton bollworm. The second category is resistant to biochemical substances, such as gossypol, high tannin, high-class terpene content of the group. But the effect is not very good, the development is limited. In recent years, with the combination of genetic engineering and breeding, breeding
