Germplasm refers to the genetic material that parents pass to their offspring. It usually refers to all living organisms carrying genetic material, including plants, roots, stems, seeds, germs and cells, as well as DNA fragments. Agricultural and forestry germplasm resources refer to the basic materials for breeding crops and new varieties of forests, including various crops, cultivars of forest trees, reproductive materials of wild species, and genetic materials of various crops and forests artificially innovated using the above-mentioned propagation materials. Germplasm resources are the carrier of genetic diversity of crops and forests, and also an important component of species diversity. The basic materials for agroforestry are important strategic resources of the country.
Through the above introduction, we can clearly understand that germplasm resources are very important non-renewable resources. At this stage, the work to be done is to protect the germplasm resources for the actual situation in China. The protection and utilization of quality resources started late, so the main way is to use germplasm resources and other important conservation facilities construction and technology to speed up the process and process of germplasm conservation to meet the needs of China's agroforestry development.
The germplasm resource bank refers to the preservation facility that protects the germplasm resources, but it is not only a preservation facility, but also equipped with a powerful management system. After the germplasm, forestry and other germplasm resources are collected, the first registration is required. The time, location, latitude and longitude, initial quality, quantity and packaging of the seeds will be recorded in the database for documentation and management. After processing, it can meet the requirements before it can enter the germplasm repository. Through the germplasm resource management system, managers can clearly guide the details of the resources stored in the resource pool, and facilitate the subsequent development and utilization of various germplasm resources, which can be readily available to scientific research, teaching and breeding units. And international exchanges.
