The Chinese Academy of Agricultural Sciences announced major new advances in agricultural science and technology throughout the academy

The Chinese Academy of Agricultural Sciences has announced that hybrid rice non-fusion reproductive system, ptogenetic induction-mediated gene editing technology to speed up the process of crop precision breeding, African swine fever vaccine research, poultry vaccine immunization successfully blocked human infection with H7N9 virus and other major new advances in agricultural science and technology.
new advances in agricultural science and technology announced this time include:
hybrid rice non-fusion reproductive system. Wang Kejian research team used genome editing technology to establish a permanent fixed hybrid advantage of rice non-fusion reproductive system, successfully obtained the cloned seeds of hybrid rice, hybrid rice non-fusion reproduction from nothing breakthrough.
gene editing technology, which is induced and mediated by monolithics, accelerates the process of precise crop breeding. The team of the Institute of Biotechnology and the Institute of Crop Science combined single-sport species with gene editing techniques to achieve a one-year (two-generation) orientation improvement of breeding materials, greatly shortening the breeding cycle.
found that plant selfish genes. Wan Jianmin's team cloned selfish genes that hindered the use of rice hybrid advantages, revealed the nature of the non-Mendel genetic phenomenon caused by rice selfish genetic factors, and clarified the role of selfish genes in maintaining genomic stability and promoting species evolution.
the genetic basis of potato self-decline through the "Excellent Potato Program". In the three self-intersecting groups of potato diposomes, the Huang Sanwen research team carried out in-depth research on harmful mutations that lead to the decline of self-interleociation, which provided a theoretical basis for the design and breeding of diplix potato molecules, and also provided a reference for the analysis of the mechanism of self-confessed decline of other asexual reproductive crops.
deep understanding of peach domestication and improved molecular mechanisms. Wang Lirong's research team built the world's largest database of peach multi-type variation groups, expounded the molecular evolution mechanism of peach fruit size and flavor characteristics, and provided theoretical support for peach genome selection breeding.
Ashdan yak is approved by the state. The research team has cultivated a new breed of yak Ashdan yak, which is meat-based, hornless, stable genetic performance, good meat production performance, strong resistance, high reproductive performance, gentle temperament, is the first special yak breed suitable for feeding.
made important progress in the research and development of swine fever vaccine in Africa. Laboratory phase studies have shown that two of the vaccine candidate strains have good biosecurity and immune protection. Researchers have established a seed bank for the production of two vaccine candidates, initially optimizing the cell culture and freeze-dried processes of the candidate vaccines.
vaccine has successfully blocked human infection with the H7N9 virus. ChenHuaLan research team developed an efficient H5/H7 two-price avian influenza inactivated vaccine, a large number of applications not only effectively blocked the H7N9 virus in poultry epidemic, but also in blocking human infection with H7N9 virus achieved immediate results.
large-scale application of new pesticides of plant immune-induced protein. The Biocicide Innovation Team at the Plant Conservation Institute has created a new process for the preparation and preparation of the highly effective protein pesticide Arterin.
of standardized industrialization of the prevention and control technology of the technology. Zhang Youjun research team to improve the "sun high temperature mules" prevention and control of the new technology, in 2018 the technology in China's main vegetable production area to promote the application of 4.739 million mu, to promote China's main production area of leek pass rate greatly increased.
wan Jianmin, vice president of the Chinese Academy of Agricultural Sciences, said the above-mentioned scientific and technological achievements show the latest significant progress in the scientific and technological work of the whole hospital in the past two years, representing the innovative ability and industrial contribution of the "national team" of agricultural scientific research.
