Breeding and extension of new wheat variety Zhongmai 895 with high yield, good noodle quality, and outstanding heat tolerance (Prof. He Zhonghu’s team at Institute of Crop Sciences)
High temperature during grain-filling stage is a limiting factor for wheat production in Yellow and Huai Valley, and breeding methodology has been established for improving heat tolerance in wheat. New wheat variety Zhongmai 895 with high yield, good quality, and outstanding heat tolerance was developed, with accumulated sowing acreage of 3 million ha, while the maximum annual sowing acreage of 70... -
Developing of Zhonghuang 6106, a new transgenic soybean with tolerance to glyphosate (Prof. Qiu Lijuan’s team at Institute of Crop Sciences)
To address the challenges of high cost and poor efect of current weed management in soybean production, we innovated soybean genetic transformation technology and glyphosate tolerance identification technology, and constructed a transgenic soybean breeding system. Using the genes owning intellectual property, we developed Zhonghuang 6106, a new transgenic soybean with high tolerance to the broad-s... -
Deciphering the resistance mechanism of important vegetable pests to insecticides (Prof. Zhang Youjun’s team at Institute of Vegetables and Flowers)
The resistance evolution of vegetable pests in the field in China is becoming more and more serious, but the resistance mechanism is still unclear. This study has discovered the pivotal signal pathways for orchestrating the resistance of the important vegetable pests including the whitefly (Bemisia tabaci) to the chemical insecticide imidacloprid and the diamondback moth (Plutella xylostella) to t... -
Key technology of nutritional modulation for quality egg production had been developed (Prof. Qi Guanghai’s team at Institute of Feed Research)
To conquer the technological bottlenecks of quality egg production, the group initiated the innovative study of eggshell ultrastructure based on the new concept of “corresponding characteristics between time sequence and space location”, and established the nutritional modulation technology of eggshell quality with micro-nutrients, which can decrease the broken egg percentage by more than 35 perce... -
Solve the complex genome assembly problem of Longjing tea cultivar and reveal the origin and evolution of the tea plant (Prof. Yang Yajun’s team at Tea Research Institute)
The high-quality chromosome-scale genome of ‘Longjing 43’, a representative tea plant cultivar in China, was obtained by using the self-developed third-generation sequencing assembly algorithm to solve the complex genome assembly problem of tea plant genome with high heterozygosity and high repeat sequence ratio. Based on the in-depth resequencing of 139 tea accessions from around the world, the o... -
Developing large-scale digital soil maps covering the whole country of China (Prof. Zhang Weili’s team at Institute of Agricultural Resources and Regional Planning)
Large amount of paper soil maps and archives as well as data from soil surveys were kept by diferent counties and provinces in China. For integrating soil information from heterogeneous resources, however, the existing methods cannot solve the scientific and technical challenges and problems. Combining the methods of soil science, artificial intelligence, data science and cartography, a new method... -
Major breakthroughs in critical technologies and patterns of toilets renovation in typical rural areas (Prof. Zheng Xiangqun’s team at Agro-Environmental Protection Institute, Ministry of Agriculture and Rural Affairs)
The team carried out a monitoring and assessment of rural toilet waste in 18 provinces throughout China for the first time, identified the regional characteristics of the harmlessness in rural toilet waste of China. A series of rural toilet conversion techniques and equipment were developed, such as unpowered integrated new compost household toilet, double-layer insulation septic tank, rainwater r... -
The overall straw-barrier removal and high quality machine-seeding technology significantly improved the sowing quality under the condition of straw returning to the field (Prof. Hu Zhichao’s team at Nanjing Institute of Agricultural Mechanization of MARA)
Initially proposed the overall straw-barrier removal and fine-coverage seeding technology and equipment of straw-returning machine based on the combination of evenly-covered translocated smashed stubble and regularly inter-row windrowing of lateral-displaced smashed stubble. It can overcome the technical bottleneck of straw blocking, seed-hanging and seed-exposuring, which commonly existed in mach... -
Clinical trial for the live attenuated African swine fever virus vaccine proves the vaccine is safe and effective in the field (Prof. Bu Zhigao’s team at Harbin Veterinary Research Institute)
Under the powerful leadership and instruction of the Ministry of Agriculture and Rural Afairs of China and CAAS, the Harbin Veterinary Research Institute promoted the research and development of African swine fever virus vaccine actively, steadily and orderly. Bu Zhigao’s team developed a safe and efective seven-gene deletion attenuated vaccine (HLJ/18-7GD strain). They have successively completed... -
Successful creation of new drug changed the situation that no drugs were available for the control of drug resistance of coccidia in China (Prof. Xue Feiqun’s team at Shanghai Veterinary Research Institute)
The team independently developed the first new triazine anti-coccidiosis veterinary drug with completely new chemical structure, Ethanamizuril, in China. This drug has outstanding characteristics such as high safety, wide anti-coccidiosis spectrum and excellent efect. It improves the prevention and treatment of coccidiosis. At the same time, the research results have broken through the key technol...
