对自然界的生物来说 ,保护天然群体的基因库 ,维持生物多样性是种质资源开发和保护的主题之一[1] 。生物多样性包括 3个层次 :生态系统多样性、物种多样性和遗传多样性[2 ] 。其中 ,遗传多样性的研究是其重要的组成部分 ,又是物种多样性的基础 ,是评价自然生物资源的重要依据。
For nature’s creatures, conserving natural populations of gene banks and maintaining biodiversity is one of the main themes for the development and conservation of germplasm [1]. Biodiversity includes three levels: ecosystem diversity, species diversity and genetic diversity [2]. Among them, the study of genetic diversity is an important part of it, which is the basis of species diversity and an important basis for evaluating natural biological resources.
