According to the statistics of plant taxonomy, the list resources are not only rich in species, belonging to 35 families 192 genera and 7 12 species, but also 80% of these germplasm are collected from China, and many of them are endemic to China, of which 60% are domestic local variety resources, and 10% are rare, rare and wild relatives.
These resources are formed by thousands of years of natural evolution under different ecological conditions, and contain all kinds of potentially available genes, which are valuable wealth of the country and the basis of human reproduction and survival. The state collects these resources as strategic resources and preserves them for future generations. With the increase of storage quantity and species diversity and the extension of storage time, the storage resources of the national treasury are playing an important role.
Expanding the functions and tasks of national data bank.
1, responsible for the long-term preservation of agricultural germplasm resources in China and the medium-term preservation and distribution of grain agricultural germplasm resources.
2. Study the theory and technology of low-temperature preservation of agricultural plant germplasm resources, and develop early warning, monitoring and updating technologies to ensure the low-temperature safe preservation of germplasm resources.
3. Study the theory and technology of long-term in vitro conservation of special germplasm such as asexual crops and stubborn seed crops, and explore and develop new methods and technologies for germplasm resources conservation.
4. Formulate the management standards and technical specifications of the germplasm bank, and preserve the germplasm resources safely for a long time. Coordinate with relevant departments at higher levels to do a good job in the management and research of the national low-temperature germplasm resources bank, and promote the improvement and development of the research level of agricultural germplasm resources conservation in China.
