China's GM cotton has also been a breakthrough
The high-tech project "Cotton factory-based transgenic technology system" undertaken by the Cotton Research Institute of the Chinese Academy of Agricultural Sciences, etc., has recently passed expert appraisal. It is reported that the new varieties of genetically modified cotton supported by this technical system have been bred to eight, and more than 32 million mu of transgenic insect-resistant cotton have been promoted, which has made China a place in this high-tech field. In recent years, genetically modified crops have become the fastest-growing high-tech crops in the world. Between 1996 and 2003, the global area of ​​genetically modified crops has increased by nearly 40 times. China's transgenic crops are dominated by transgenic insect-resistant cotton. In the face of fierce international competition, China’s transgenic cotton research and industrialization has achieved a series of major breakthroughs with the support of the state, and a new breed of genetically modified insect-resistant cotton has been cultivated and acquired. Intellectual property. With the strong support of the Ministry of Science and Technology, the Ministry of Agriculture, and the relevant departments of Henan Province, the Cotton Research Institute of the Chinese Academy of Agricultural Sciences launched a study of the "cotton factory-based transgenic technology system." Through years of efforts, it has finally built an efficient, factory-built cotton. The transgenic technology system has an annual output of more than 6,000 transgenic cottons, effectively reducing the cost of cotton genetically modified organisms. Through optimization of transgenic technology systems, genes such as insect resistance, disease resistance, and fiber quality improvement have also been transferred to more than 20 major cotton varieties. In addition, they have also successfully applied plant grafting technology to the rapid transplantation of transgenic cotton. The survival rate reached more than 90%, which effectively solved the problem of low survival rate of cotton transgenic seedlings transplanted. Experts believe that this achievement is at the leading level of domestic similar research and has reached the international advanced level. Driven by this technology, the planting area of ​​transgenic insect-resistant cotton in China has rapidly expanded. According to Dr. Yu Shuxun, head of the Cotton Research Institute of the Chinese Academy of Agricultural Sciences, in 1998, the planting area of ​​transgenic insect-resistant cotton in China was 3.8 million mu, of which 95% was foreign insect-resistant cotton, and domestic insect-resistant cotton accounted for only about 5%. This year, the country's total area of ​​transgenic insect-resistant cotton has reached more than 46 million mu, and the cultivated area of ​​domestically-transplanted insect-resistant cotton has reached about 70%, of which Hebei, Shandong, Henan and Anhui provinces have achieved 100% planting. At present, the planting area of ​​domestically produced transgenic insect-resistant cotton has reached more than 7,000 million mu, and the average income per mu has increased from 140 yuan to 160 yuan, which has been warmly welcomed by the cotton farmers.
