Industrialized cotton transgenic technology system built
According to the Ministry of Science and Technology, Chinese scientists and technicians have now established an efficient, factory-based cotton genetically modified technology system, and have assembled a variety of genetically modified technologies to achieve assembly line operations, with an annual output of more than 6,000 transgenic cottons, effectively reducing cotton genetically modified operations. cost. Experts believe that this achievement has reached the international advanced level. The Institute led by Dr. Yu Shuxun, the chief scientist of the National High-Tech Agriculture Theme and the head of the Cotton Research Institute of the Chinese Academy of Agricultural Sciences, transferred the genes for insect resistance, disease resistance, and improved fiber quality through the optimization of industrialized transgenic technology systems. More than 20 major cotton varieties have reduced Agrobacterium-mediated gene turnover to 6 months. Dr. Yu said that the efficiency of this transgene was significantly improved compared with published methods. In 1998, China planted 3.8 million mu of genetically modified insect-resistant cotton, 95% of which were foreign insect-resistant cotton, and only 5 of domestic insect-resistant cotton. %about. At present, the planting area of ​​domestically produced transgenic insect-resistant cotton has reached more than 7,000 million mu, with an average increase of 140 yuan to 160 yuan per mu, which has increased cotton farmers' income by more than 10 billion yuan.
