棉铃虫是棉花的主要害虫之一。近年来,防治棉铃虫由于大量施用农药,至使棉铃虫产生了高倍抗药性,同时也杀伤天敌,破坏了生态平衡。为此,培育棉花抗棉铃虫品种是非常必要的。研究较多的是无蛋腺光叶性状。无蜜腺受两对隐性基因he_1和he_2所控制,可使棉铃虫饥饿,因而缩短其生命和降低其生育力,光叶性状受一对显性基因Sm控制,可以减少棉铃虫在棉叶上的产卵量。1982年我们选出了 Cotton bollworm is one of the major pests of cotton. In recent years, the control of cotton bollworm due to the large number of pesticides, cotton bollworm to produce a high resistance, but also kill natural enemies, undermining the ecological balance. Therefore, cultivating cotton bollworm varieties is very necessary. More research is no egg gland leaf traits. No nectar was controlled by two recessive genes he_1 and he_2, which could starve cotton bollworm, thus shortening its life and reducing its fertility. Light traits were controlled by a pair of dominant genes Sm, The amount of eggs on the. We chose it in 1982
