Cotton scale transgenic technology system platform built

The project “Construction and Application of Large-Scale Cotton Transgenic Technology System Platform” led by Dr. Li Fuguang of the Cotton Research Institute of the Chinese Academy of Agricultural Sciences was completed recently. Researchers have effectively assembled a variety of genetically modified technologies, realized assembly line operations, established an efficient, factory-based cotton transgenic technology system, and produced more than 6,000 transgenic cotton plants per year, reducing the cost of genetically modified genes; broadening the genes of receptors. In the range of type, insect resistance, disease resistance and other genes were transferred to 27 major cotton varieties, and plant grafting technology was successfully applied to the rapid transplantation of transgenic cotton, and the survival rate reached over 90%. The use of this technology system to obtain genetically modified materials to breed 15 new varieties of transgenic cotton, so that the domestic market share of transgenic insect-resistant cotton increased from 5% in 1998 to about 62% in 2004; in Handan, Shandong, Henan, Hubei, The six provinces of Fujian and Su-producing cotton cumulatively promoted more than 61.44 million mu of domestically-produced transgenic cotton, and achieved social and economic benefits of 9.16 billion yuan.
