The seed industry is a "chip" that promotes the development of high-quality agriculture, and germplasm resources are the material basis for promoting modern seed industry innovation. The rapid development of the seed industry is inseparable from rich and diverse germplasm resources. At the same time, laying a solid material foundation is particularly important. In the process of strengthening the protection, development and utilization of germplasm resources , the germplasm resource bank has played an important role.
With good genes, good varieties can be bred. Many of the good characteristics of new varieties are extracted from wild species, so without rich genetic materials as support, the development of the seed industry will be difficult. So where are the germplasm resources? They exist in vast nature, some have been discovered and developed, and some have not yet been excavated, and unfortunately, with the acceleration of urbanization and the speed of land transfer, coupled with global climate change, disaster-prone climate and Affected by the disease, many germplasm resources in our province, especially the niche where wild plants depend on, have been deteriorating or even disappearing. Many rare resources and ancient local varieties that have been passed down from generation to generation are gradually disappearing. Some ancient local varieties and national first- and second-level protection are gradually disappearing. Many wild plants on the list are endangered. In order to retain the excellent germplasm resources in nature as soon as possible and accelerate the development and application, the construction of germplasm resource banks is urgent.
If the germplasm resource bank is subdivided, it can be divided into agricultural, forest, animal husbandry, fishing, and grass germplasm resource banks. Although the classification is different, the functions are the same, which is to better collect, preserve, research and use And popular science germplasm resources. So what technologies does the germplasm resource bank have to achieve long-term preservation? The original germplasm resource bank is equipped with advanced instruments and equipment such as heat insulation, humidity insulation and air conditioning, and an intelligent monitoring system is used for monitoring and management. It can maintain a low temperature and dry environment all year round, so that the biological genetic material will not be lost for several years or even a hundred years. Original heredity and germination ability. In addition, the germplasm resource bank is not only a preservation bank, but also has the function of resource management, which can further promote the accelerated development and utilization of germplasm resources, and promote the high-quality prosperity and development of China's seed industry.
