China has a vast territory and different climatic environments. As a result, many wild, original species and crop varieties with local characteristics are produced. These crop varieties are valuable assets of these places. If they can be applied to agricultural development, they will become extremely Great promotion of local agricultural development. To make good use of these characteristic crop germplasm resources, it is necessary to use the germplasm resource bank of the crops to carry out the collection and preservation of wild, original species, and local featured varieties, and lay the foundation for the safe protection and efficient use of local crop germplasm resources. .

During the process of survey and collection, the staff found that although the yield of seeds used in many areas was not high, they were of high quality and were very tasty. They were also preferred to hybrid seeds in the local area. This shows that the seeds of these crops contain precious genes. If these genes are excavated and improved, not only can the yield of the crop varieties be improved, but the quality of the crops can also be significantly improved. Moreover, many of these crop germplasm resources are endemic to the local area, and these planting resources are excavated and collected. It is very important to promote the development of local characteristics of agriculture. Therefore, in the process of excavation, the staff will start with these precious crop germplasm resources and register the collected germplasm resources into crop germplasm resources. Long-term preservation in the library.
During the process of survey and collection, since the surveyed germplasm resources of crops cover grain, fiber, oil, vegetables, fruit trees, pasture, green manure, etc., both species and quantities are relatively large, if they do not do a good job of preservation in time, Therefore, it is very easy to cause the loss of crop germplasm resources. Therefore, applying the crop Germplasm Bank to establish a gene bank of crop endemic and local varieties can not only help collect more germplasm resources, but also find more unique resources, and can It lays the foundation for the creation of new germplasms with high yield, high quality, high efficiency, broad adaptability and outstanding target traits and breeding value, and provides the most important source of production information for the development of local characteristic agriculture.
