In nature, there are abundant products and rich plant species. Currently, the seeds used for sowing in agriculture are actually only a small part of many species in nature. In order to further tap the productive potential of crops and support the sustainable development of modern agriculture, it is necessary to continuously collect and excavate excellent germplasm resources, and use the germplasm resource bank for protection, through subsequent identification and evaluation of these germplasm resources. The use of new and improved varieties of crops will not only increase production and increase quality, but also preserve biodiversity and create important environmental conditions for human development.
Germplasm resources are the material basis for crop breeding, genetic research and production and utilization, and are of great significance for the sustainable development of modern agriculture. In the process of collection, conservation, identification, evaluation and utilization of germplasm resources, germplasm resources play a very important role. The germplasm resource bank is an important facility for preserving germplasm resources, an ideal medium for long-term storage of germplasm resources, and also a basic platform for resource collection, preservation and utilization. In the actual production and life, the good vision of the germplasm resource bank mainly includes the following two points:
1. Strengthening the collection and preservation of the current With the acceleration of economic development and the acceleration of urbanization, the environment for the survival of many germplasm resources has been destroyed. In addition, the large-scale promotion of the varieties of excellent clones in recent years, some local groups with special characteristics The breed is in danger of being lost. In this context, in order to preserve the genes of these outstanding germplasm resources in nature and enable them to continue to be used by us, we must use the germplasm resource bank to enhance the collection and preservation of excellent germplasm resources.
2. Another great vision to strengthen the exploitation and utilization of germplasm resources is to strengthen excavation and utilization. Germplasm resources are preserved and collected in the germplasm resource bank. They are categorized and stored separately and managed using management software. This can be further strengthened. The use of these resources has been enhanced by the development of large-scale phenotypes and refined genotypic identification, excellent gene excavation and validation, creation and utilization of new germplasm resources, and the development of more and better new crop varieties.
