Taking Advantage Of Upland Cotton For Improving Cotton Quality: A New Breakthrough In Cotton Genome Research In Huazhong Agricultural University

The reporter learned from the 2014 international cotton genome project conference in Wuhan that the genome sequencing of the island cotton was carried out by Huazhong Agricultural University. Through the analysis of the genome of the island cotton with high quality fiber and disease resistance, we can use the island cotton gene resources to enhance the fiber quality and disease resistance of upland cotton.

According to Professor Zhang Xianlong, member of the research team of cotton genetics improvement in Central China Agricultural University, and Professor Zhu Longfu, 95% of China's raw cotton is derived from upland cotton. Upland cotton has strong adaptability and high yield, but fiber length is short and susceptible to Verticillium wilt. Sea island cotton is mainly grown in Xinjiang, China. It has fine fiber length, fine, strong and Verticillium wilt resistance. In recent years, cotton varieties have strong similarity and low disease resistance, especially the occurrence of Cotton Verticillium wilt, which is a serious threat to the development of cotton industry and the safety of cotton production in China.

　　 Central China Since 2000, Kasetsart University has carried out the research on the mechanism of island cotton fiber development, and started sequencing of the island cotton genome 3 years ago. Scientists repeatedly improved the analysis method, and finally separated the two sub genomic sequences of A and D highly similar to the island cotton, and discovered the special mechanism of the island cotton fiber development. On this basis, the composition and evolution of the cotton genome were further analyzed. By identifying the genes that determine the quality fiber formation of the island cotton and the genes resistant to Verticillium wilt, the fiber quality and Verticillium Wilt Resistance of upland cotton were improved.

The research results have attracted the attention and attention of scientists at the 2014 international cotton genome conference. More than 300 cotton research experts from more than 10 countries in the United States, Australia, France and more than 20 scientific research institutes in China have been fully affirmed.

　　 recent years The research team of Huazhong Agricultural University's cotton genetic improvement team has made remarkable achievements in basic research of cotton germplasm resources innovation, genetic analysis of complex agronomic traits, cotton Verticillium wilt resistance, fiber development and mechanism of multiple resistance. The research results have published more than 80 academic papers in international academic journals, showing the strength of the team in the field of cotton basic research. At the same time, the team also cultivated 6 new cotton varieties, of which "Hua Za cotton H318" has. high yield It has been widely applied in the Yangtze River Basin for its stable production, high quality and wide adaptability. It has produced remarkable economic and social benefits.

Carbon fiber and other new materials will be supported by the state.

Carbon fiber, rare earth and high temperature resistant metal materials are expected to become new materials supported by the state. China's new materials will focus on three major areas, including carbon fiber, and the Ministry of industry and Commerce will focus on supporting policies.

At present, the Ministry of industry and information technology is speeding up the demonstration of major projects, studying the establishment of a new material risk compensation mechanism, improving the comprehensive supporting policies such as finance, taxation, finance and insurance, and forming a policy force to jointly promote the development of the new material industry. According to the plan, the Ministry of industry and Commerce strives to accelerate the development of key areas including the new material industry through 10 years' efforts to push China into the world's manufacturing powerhouse as a whole.

New materials, information and energy are the three pillars of the current world's new technological revolution. According to the Ministry of industry and information technology, the scale of new material industry has exceeded 1 trillion and 200 billion yuan, with an average annual growth rate approaching 25%. However, in many areas, new materials in China are still short boards, so we must further increase support for new materials.

At present, carbon fiber, rare earth and high temperature resistant metal materials are expected to become new materials supported by the state, and new display materials will also be included. However, the reporter has learned that the graphene materials, which are very much concerned by the market, are more inclined to support later because they are more forward-looking.

Su Bo, Vice Minister of the Ministry of industry and commerce, said that vigorously developing the new material industry, such as carbon fiber and composite materials, is of great significance for improving the market competitiveness of China's raw material industry, safeguarding national defense safety and promoting China's industrial development from strength to strength.
