In the agricultural sector, we often see such news, that is, the establishment of a germplasm resource pool of Chinese herbal medicines has provided important support for the protection and development of Chinese herbal medicines. So what is the germplasm resource bank ? Before answering this question, you first need to understand what germplasm resources are.
Germplasm refers to the genetic material passed on to the offspring by the parent of the organism. It is often found in specific breeds. Germplasm resources are also called genetic resources. Ancient local breeds, newly cultivated varieties, important genetic materials, and wild The marginal plants belong to the range of germplasm resources. The germplasm resource bank can be regarded as a “gene pool†for storing various germplasm resources. It stores various germplasm resources collected together, and uses instruments and equipment to control the storage environment and realize germplasm resources. Long-term safe storage.
In the development of modern agroforestry, the role of germplasm resources has become more and more important. Because breeding is inseparable from the original genetic material provided by these germplasm resources, if the germplasm resource bank is not used and effective measures are taken to protect and utilize these useful germplasm resources, the subsequent breeding work will be due to the lack of genetic material. Can't expand. The germplasm resource bank has a strong long-term preservation function. It can excavate and collect seeds of various crop varieties and store them scientifically, so that the germplasm still has original genetic characteristics and is very much after decades or even hundreds of years. High germination power, for the improvement of varieties, cultivating new varieties with high yield, high quality and strong resistance, and providing rich germplasm and research materials for the theoretical study of biology is of great significance.
At present, all localities attach great importance to the protection and utilization of germplasm resources, and have actively invested in the construction of various special germplasm resources pools, and established a number of Chinese herbal medicine germplasm resources, flower germplasm resources, and forest germplasm resources. The establishment of these libraries has provided a solid material foundation for crop breeding and production in China, and promoted the rapid development of agroforestry.
