The qualitative resources of crop species are formed through thousands of years of natural evolution under different ecological conditions. They contain a variety of potentially usable genes. They are the precious wealth of the country and the basis for human reproduction and survival. To vigorously develop modern agriculture and forestry, it is necessary to further strengthen the protection and utilization of germplasm resources. After years of development, the storage conditions of crop germplasm resources have been continuously improved, and the storage technology of germplasm banks has become more and more advanced, which is of great significance to the selection of high-quality germplasm, the selection of forest tree species, and the promotion of high-quality development of agriculture and forestry. Let's introduce the national crop germplasm bank in detail below. Establishment of national crop germplasm resource bank: The National Crop Germplasm Bank of China was established in 1986 to undertake the long-term strategic preservation and supply of germplasm resources of national crops and their wild relatives. At present, the total number of crop germplasm resources in my country is 520,000, ranking second in the world. . Its preservation center contains 12 cold storages, including 5 long-term storage cold storages, 6 mid-term storage cold storages and 1 temporary storage cold storage. Long-term storage cold storage, the storage temperature is controlled at -18℃±2℃ all year round, and the relative humidity (RH) is controlled below 50%. It is mainly used for long-term preservation of crop varieties collected from all over the country, including farm species, wild species and eliminated Bred varieties and so on. The storage conditions of the mid-term warehouse are -4℃±2℃, relative humidity <50%, and the seed storage life is about 10 to 20 years. The resources stored in the mid-term bank can be provided to scientific research, teaching and breeding units at any time for research, utilization and international exchange. 1 Temporary storage cold storage (+4℃) for the delivered seeds to be temporarily stored before entering the medium and long-term storage cold storage. The new national crop genebank will be completed in August this year, with a storage capacity of 1.5 million copies, realizing full intelligence, and becoming the national genebank with the largest amount of monomer in the world. Establishment of national crop germplasm resources database: The National Crop Germplasm Resource Database is constructed and maintained by the National Crop Germplasm Information Center of the Institute of Crop Science of the Chinese Academy of Agricultural Sciences. After more than 20 years of hard work, it has the basic information and morphological characteristics of more than 200 crops and 390,000 germplasm. And six aspects of data such as biological characteristics, quality characteristics, stress resistance, pest resistance and other characteristics, the data volume is about 200GB. The national crop germplasm resource database is open to the society for sharing on the Internet through the China Crop Germplasm Information Network. Through the national crop germplasm resources database, we can fully grasp and understand the situation of crop germplasm resources in my country, promote the protection, sharing and utilization of germplasm resources, provide excellent germplasm information for scientific research and agricultural production, and provide popular science information for the public , To provide the country with decision-making information on resource protection and sustainable utilization. Seeking Top for the construction of germplasm resource bank: Top Yunnong provides professional germplasm bank construction plans, undertakes the design, installation and after-sales service of various seed storage warehouses, germplasm resources banks and other projects, and can build professional germplasm according to the requirements of crops and forest germplasm resources protection projects Resource storage library, welcome to inquire for in-depth understanding of the program details!

The third national census and collection of agricultural germplasm resources is planned to use 3 years to complete the largest census of germplasm resources since the founding of New China, complete the census of crops, livestock, poultry, and aquatic germplasm resources, and find out the national germplasm resources. The type, quantity, distribution, main traits and other family backgrounds of qualitative resources. After the census of germplasm resources is completed, there will be another 100,000 more unique local varieties and wild resources in my country’s genebank.
