The Second Generation Of Spangenic Cotton In China Is At The Leading International Level.

The research of the second generation of spangenic cotton in China has jumped to the leading level in the world, and has independent intellectual property rights such as inventions and patents, so as to lay a solid foundation for getting rid of the long-term dependence on imports of high-end cotton. This is another important scientific and technological achievement in our high-tech field after the spangenic insect resistant cotton.

This is the news from the 20 expert meeting of the expert group meeting on cotton breeding project.

According to Li Jiayang, Vice Minister of agriculture and President of Chinese Academy of Agricultural Sciences, diseases and insect pests and fibre Low quality is the two stubborn disease that has long troubled the development of cotton industry in China. In the 90s of last century, Chinese scientists developed the first generation of genetically modified cotton with independent intellectual property rights, the Bt spangenic cotton bollworm, which successfully resisted the harm of cotton bollworm, and made the market share of the domestic spangenic insect resistant cotton expanded from the initial 5% to over 95%. So far, spangenic insect resistant cotton is still the largest spangenic crop in China.

Li Jiayang said that with the support of major projects for the cultivation of new varieties of genetically modified organisms, the Cotton Research Institute of Chinese Academy of Agricultural Sciences, Beijing University, Fudan (micro-blog) University, Southwestern University and other scientific research institutions and universities researchers unite and cooperate, give full play to our accumulated experience and technology in the first generation of spangenic cotton research, launch joint research, and finally get a major breakthrough in the cultivation of genetically modified high-quality fiber varieties and materials.

Among them, the "cotton basket 70" selected by the Cotton Research Institute of Chinese Academy of Agricultural Sciences is made from the cross breeding of high quality introgression lines of the island cotton and spangenic insect resistant cotton lines and molecular polymerization technology, and the length of the cotton material fiber is 32.5 millimeters, so as to achieve the high quality cotton standard. New high quality boll RRM Transgenic Cotton Germplasm from the Cotton Research Institute of Chinese Academy of Agricultural Sciences and Fudan University Material Science The weight of single boll can reach 7.5 grams, which is significantly higher than that of common cotton varieties, and its boll setting ability is more than 20% higher than that of ordinary cotton varieties.

Yu Shuxun, director of the Cotton Research Institute of Chinese Academy of Agricultural Sciences, said that the inherent quality of cotton fibers in China is relatively poor. The quality raw cotton that spun 60 or more high count yarns is heavily dependent on imports. It has become a major bottleneck restricting the upgrading of cotton textiles in China. If China's cotton can be spun from 32 spinning yarn to 60 spinning yarn, the grade of cotton yarn and its processed products will be raised, and its price will increase by about 50%. This is of great significance to comprehensively enhance the international competitiveness of China's entire cotton industry chain.
