China Youth Daily Client News (Xie Peng, China Youth Daily, China Youth Network Reporter Lin Jie) Recently, the 2023 China (Zengcheng) Silk Miao Rice Industry High-quality Development Conference was held in Guangzhou. At the scene, the Zengcheng Research Institute of Guangzhou National Agricultural Science and Technology Innovation Center was unveiled, and the big data of silk miao rice germplasm was released, and the genetic distance analysis was carried out through 100 billion omics data, and the whole country of Zengcheng silk miao rice was traced"Blood relatives"。

As the best representative of Lingnan high-quality rice, Zengcheng Silk Miao Rice has a history of more than 500 years and is now"There are five constants in the north and silk seedlings in the south"Deeply rooted in the hearts of the people, Simiao rice has become one of the synonyms of China's high-end rice. How to use scientific means to trace the roots of Zengcheng Silk Miao Rice, find out the family background, clarify the relationship, and find specific genetic information is not only of great significance to the sustainable development of Zengcheng Silk Miao Rice, but also provides tools for industry breeding.
For 3 years, Guangdong Provincial Department of Agriculture and Rural Affairs"Bay Area Germplasm Digital Port"It has gathered 856 core germplasms and more than 20,000 associated germplasms, and the omics data of genome and phenotype have exceeded 100 billion"Phenotype + genotype"Identification was established"Five-in-one"The identification system can quickly trace and determine the genealogical relationship of germplasm resources.
Tang Xiangru, a professor at South China Agricultural University, introduced that in 2022, the Ministry of Agriculture and Rural Affairs will release 29 leading rice varieties in the country, including 19 indica rice varieties"Made in Guangdong""Guangdong core"There are 11 varieties, accounting for more than half, which shows the importance of germplasm gene research. "Bay Area Germplasm Digital Port"It provides a macro vision for all researchers engaged in germplasm research, which can avoid low-level repeated research on the one hand, and on the other hand, it is conducive to accurate matching and efficient breeding, and helps the development of silk miao rice industry from the core germplasm.
How to will"Souvenirs"becomes"Golden gluttony", the good land, good seeds, good laws, good tools, good products, good systems and many other chains beaded into a chain, to create a multi-integrated demonstration of the whole industry chainRelying on the Guangzhou National Agricultural Science and Technology Innovation Center, the agricultural department of Zengcheng District, Guangzhou City, through the agglomeration of innovative elements, the integration of key technologies, the concentration of affiliated enterprises and advantageous industrial clusters, connects experts, chains industries, and scientific and technological innovation empowerment, and opens up the whole chain and whole process from scientific and technological innovation to industrial application.
The conference decided that in the future, it will be held once a year in Zengcheng, Guangzhou, the hometown of silk miao rice in China"Counting rice, Zengcheng released"The conference will announce the big data of scientific research and science and technology laws of silk miao rice for the whole country, and build a bay area for the scientific and technological development of the rice industry with a platform for scientists, entrepreneurs and elements in the rice industry"Macro Eye"with"Wisdom Brain"。
