由中国农科院与国内数十家单位合作,继育成国抗1号、中棉所29号、晋棉26号等十多个单价抗虫棉品种之后,新近又取得了双价抗虫棉育种的突破性进展。运用花粉管理技术,将两种杀虫基因导入了一批主栽品种,如石远321、晋棉12号、中棉所19号、中植372等,共获得了数十个双价基因抗虫棉株系,已从中选育出了十几个抗虫性能好、优质丰产品系。其中SGK 321(受体为石远321)表现十分优良.日前通过了农业部农业生物基因,工
By the Chinese Academy of Agricultural Sciences and dozens of domestic units, following the Yucheng Guokang 1, China Cotton Plant 29, Jinmian 26 more than a dozen price of insect-resistant cotton varieties, the newly obtained bivalent insect-resistant cotton Breeding breakthroughs. Using pollen management techniques, two insecticidal genes were introduced into a number of main cultivars, such as Shi Yuan 321, Jin Mian 12, Zhong Mian Su 19, Zhong Zhi 372 and so on. A total of dozens of bivalent gene antigens Insect cotton strains, have been bred from more than a dozen insect resistance performance, high quality and high yield lines. One SGK 321 (Receptor for far 321) performance is very good. Recently adopted by the Ministry of Agriculture, agricultural biological genes, workers
