Guangdong is the earliest provinces to carry out the construction and research of germplasm resource libraries in China. The Guangdong Provincial Party Committee and the Provincial Government have always attached great importance to the development of the seed industry, especially the basic work in the field of germplasm resources. By increasing the investment in fiscal funds, the research on the collection, preservation and innovative utilization of germplasm resources has been strengthened. In 2018, the "Guangdong Agricultural Outlets and Genior Genior Resource Resources Library (Garden) Construction and Resource Collection, Preservation and Evaluation" project was approved by the Provincial Department of Agriculture and Rural Affairs, and invested 50 million yuan to rely on the construction of the Provincial Academy of Agricultural Sciences. After more than three years, the project successfully completed all construction content and task indicators. After inquiry and discussion by experts, the project was agreed to pass the acceptance.

Jiang Yi said in a summary of his speech that the germplasm and resource database (garden) of the agricultural work must not only be built, but also use it well. The key to crop quality resources is to maximize use. The first is to accelerate the concentrated preservation of resources. It is necessary to make full use of Guangdong's farmers' crop quality resource protection libraries to gradually promote centralized preservation. The second is to accelerate the preliminary evaluation and in -depth evaluation of germplasm resources. It is necessary to promote the establishment of a long -term stable support for the preservation and utilization of the germplasm resources. Through in -depth evaluation of resources, strengthen excellent gene mining and functional verification, and lay the foundation for the cultivation of large breaking varieties. The third is to focus on establishing a mechanism for the exchange and sharing mechanism of germplasm resources. Accelerate the formation of agricultural work quality resources information disclosure and sharing communication mechanism, promote the construction of a digital sharing platform for the construction of agricultural type of quality resources, and realize the unified management of germplasm resources and data -based high -efficiency mining and accurate use of data. The fourth is to use germplasm resources to promote the cultivation of new varieties of major breakthroughs. Focusing on national strategic needs and the development needs of the province's advantageous industries, accelerate the core technology of the "species source", and cultivate a number of high -yield and efficient, green high -quality, water -saving machine, and special breakthroughs in special breakthroughs.

Participating leaders and experts visit

After the acceptance meeting, Gu Xingwei, Jiang Yi, Li Xudong, and the participants visited the Guangdong Agricultural Works Heritage Resources Information Exhibition Hall, Guangdong Agricultural Performance Resource Protection Library (central library), and Guangdong characteristic farmers' cropped quality resources exhibition. Gu Xingwei and other investigating the situation of various exhibition areas in detail, and understand the results of the collection, preservation, utilization and new varieties selection of seed resources. Gu Xingwei said that seeds are the "chip" of agriculture. Genome resources are the key to form a "chip" and are the key strategic resources of a country. In our province, the four major types of germplasm resource construction systems of crops, livestock poultry, aquatic products, and microbial creatures have been formed. The breeding innovation system of the process and the full chain provides a strong motivation for agricultural scientific and technological innovation and the revitalization of the breeding industry.

On the same day, the Guangdong Academy of Agricultural Plaza at the Baiyun Base of the Provincial Academy of Agricultural Sciences and the exhibition and open day of the Guangdong Agricultural Heritage Heritage Heritage Hydravania and Open Days were exposed to the "bottom of the family" of Guangdong Agricultural Works. The physical and varieties of 1,000 excellent special resources and varieties are gorgeous, including the largest rice varieties of rice breeds in my country and the largest promoting area in China, the largest high -quality rice variety in our province "Meixiang Occupy 2", leading Guangdong black tea, leading Guangdong black tea The "British Red Nine" of the industry's development, the "Xianjin Feng" litchi who occupied the high -end market, and the famous "Iron Pillar Winter melon", "Yue Tian No. 28" sweet corn and so on. The event attracted many employees and citizens of the hospitals to visit.

There is a dazzling, and the fruits are fragrant.

The construction of the "Guangdong Agricultural Outlet Promotion Resources Library (Garden) Construction and Resource Collection, Review, and Evaluation" project has built the largest and most comprehensive agricultural type of quality resource protection database in South China, which greatly improved the province's seed safety resource preservation The ability has laid a solid foundation for the implementation of the revitalization of the seed industry.

Through the implementation of the project, relying on the provincial Academy of Agricultural Sciences to build a more complete national and provincial and ministerial -level agricultural work quality resource protection database (garden), native protection point, separation protection database and DNA library It can accommodate more than 400,000 species of agricultural objects and 500,000 samples of germplasm genes (DNA).

The Provincial Academy of Agricultural Sciences now owns 6 national germplasm resource gardens, 3 germs of germplasm resources in the agricultural and rural ministries, 1 Guangdong Agricultural Heritage Given Resource Protection Library (central library), and provincial and municipal co -construction library (garden) 11. The Guangdong Agricultural Works Extractional Resource Protection Library (central library) is the core of the Guangdong farm -based type of quality resource protection system. After upgrading and transformation through the project implementation, the library capacity has increased from the original 100,000 to 150,000 copies. The flowers are gorgeous, and they are bright.

At present, the Provincial Academy of Agricultural Sciences has accumulated more than 63,000 farmers' types of agricultural crops, covering more than 190 crops, accounting for more than 70%of the province, ranking first in South China.
