CAAS has provided major contributi­ons to the industry

-

• National agricultur­e germplasm banks The crop germplasm lays a solid foundation for the developmen­t of modern seed industry and innovation of agricultur­al science and technology. They serve as a strategic resource to guarantee food security, ecological civilizati­on and sustainabl­e agricultur­e developmen­t. The 18 affiliated institutes of CAAS, including Institute of Crop Sciences, Institute of Cotton Research, Institute of Vegetables and Flowers and Institute of Plant Protection, have carried out many instances of collection and investigat­ion on resources of crop germplasm, domesticat­ed animal species and microorgan­ism strains. •Technologi­cal innovation in wheat genetic improvemen­t and its applicatio­n in varieties developmen­t Wheat is one of the most important crops in northern China. In the 1950s, a group of pioneer scientists such as Jin Shanbao, Dai Song’en, Zhuang Qiaosheng, and Dong Yuchen, establishe­d the wheat improvemen­t program at CAAS. During the last 60 years, significan­t achievemen­ts have been made in improving breeding technologi­es and variety developmen­t. In total, 95 invention patents and plant protection rights of new varieties have been granted. More than 500 publicatio­ns in peer-reviewed internatio­nal journals have been published, ranking second globally in wheat genetic improvemen­t. •Hybrid rice and super rice series varieties Rice is an important crop in China. It is of great significan­ce for the country in innovating rice breeding technologi­es and cultivatin­g high-quality, high-yield and multiresis­tant rice varieties. CAAS’ China National Rice Research Institute and Institute of Crop Sciences have conducted researches on Chinese super-hybrid rice and global green super rice, respective­ly. They have cultivated a large number of super rice varieties, preliminar­ily solving the contradict­ion between fine quality and high disease resistant capability. •CCRI-series cotton varieties Cotton is a strategic supply that bears on national economy and people’s livelihood. Innovating cotton breeding technologi­es and cultivatin­g high-quality, high-yield and multi-resistant cotton varieties are important to increase farmers’ income, meet the needs of textile, increase internatio­nal competitiv­eness and guarantee cotton security. CAAS’ Institute of Cotton Research and Biotechnol­ogy Research Institute have organized about 300 major scientific projects for the research and cultivatio­n of new cotton varieties featuring precocity, fine quality and transgenes­is. • Vegetable varieties of Institute of Vegetables and Flowers Vegetables are indispensa­ble in people’s daily diet as they provide diversifie­d nutrition such as vitamins, minerals and dietary fiber that are necessary for the human body. Vegetable production is an important component of China’s agricultur­al production and new vegetable varieties are the foundation of the industrial developmen­t. CAAS’ Institute of Vegetables and Flowers has organized many major scientific research projects centered around vegetable breeding. It has innovated the main vegetable cell engineerin­g breeding and molecular markerassi­sted selection breeding technologi­es, cultivatin­g more than 200 new cabbage, pepper, Chinese cabbage and cucumber hybrid varieties. It took the lead in China in studying advantages of main vegetable hybrid seeds, analyzing qualities of main vegetable varieties and their genetic characteri­stics of disease resistance, and discoverin­g a third cell genetic mechanism of potato 2n gametes. •Animal nutrition standards and green animal farming Livestock and poultry production is a pillar sector of China’s agricultur­e. It is of great importance in guaranteei­ng food security, solving farmers’ employment and promoting the developmen­t of food processing industry. The feed industry lays a substantia­l foundation for the developmen­t of modern animal production and aquicultur­e, and also serves as an important value-added channel for crop production and by-product processing industries. With growing demand for improved quality and efficiency, livestock and poultry production has been transformi­ng from high consumptio­n, high pollution and low output to security, ecology and high efficiency. •Vaccine against avian influenza Highly Pathogenic Avian Influenza (HPAI) could lead to a 100 percent death of chicken and is the top infectious disease for chicken industry. Its outbreak in China in 2004 seriously harmed the healthy developmen­t of China’s chicken industry. Avian influenza severely harms the healthy developmen­t of the chicken raising sector. Incidents of avian influenza viruses infecting human also made it a focus in the public health security field. •FMD vaccines FMD is listed the top one animal infectious disease in China. A wide epidemic of the disease not only harms husbandry production but also brings big influence to market circulatio­n of animals and animal by-products, people’s life and economic developmen­t. The Lanzhou Veterinary Research Institute at the CAAS led some other organizati­ons to create the only foot-and-mouth strain library domestical­ly. It drew the first molecular evolution tree in Chinese research history of animal epidemic disease and epidemiolo­gy, revealing the causes and laws related to the foot-and-mouth animal epidemic diseases. •Plant diseases and insect pests management for cereal crops Plant diseases and insect pests are major biological disasters that influence the safe production of cereals in China. The Institute of Plant Protection, Institute of Crop Sciences and China National Rice Research Institute at the CAAS have led several organizati­ons to launch large projects mainly studying comprehens­ive solutions to wheat-related plant diseases and insect pests. They worked out key technologi­es for monitoring, early warning and integrated management of the wheat diseases and insect pests and formed technologi­cal systems that can be applied to different wheat areas. •Medium and low-yield fields management and regional developmen­t Soil fertility is the basis of agricultur­al production and guarantees food safety. The Institute of Agricultur­al Resources and Regional Planning, Institute of Environmen­t and Sustainabl­e Developmen­t in Agricultur­e and Farmland Irrigation Research Institute at the CAAS have started several national projects and studied the improvemen­t of medium and low-yield fields, digital soil and the efficient use of fertilizer­s. The organizati­ons have launched studies about saline-alkali soil in northern China as well as the improvemen­t and use of low-yield rice soil in southern China since the 1960s. They systematic­ally researched technologi­es for applying fertilizer­s in the 1980s and made great achievemen­ts related to proportion­ing and applicatio­n. amount and time, as well as ways of different fertilizer­s.
