摘　　要：家养动物多样性的研究多年来侧重于经济性状和生态多样性及品种多样性。近几年来在遗传多样性方面取得重大进展 ,在品种聚类、系统保种、遗传多样性与经济性状和生态多态性的相关研究都取得了重要结果 ,有的已经做到数量性状基因定位、转基因和克隆动物检测等。家养动物与其野生近缘种的基因分析和利用野生种血液的育种也取得一定的效果。利用多样性鉴别技术已确认许多地方品种为中国特有种 。For years the research on domestic animal diversity has emphasized diversity of economic traits, ecological diversity and diversity of breeds. Recently, research on genetic diversity of domestic animals has developed rapidly. Research on clusters of breeds, systematic conservation, the relationships between genetic diversity and economic traits, and ecological diversity has all made great progress, including some success with QTL, and creating transgenic and cloned animals. The genetic analysis between domestic breeds and their wild relatives was applied to breeding new strains or breeds by hybridization.Evaluation methods using biotechnology have confirmed that many local breeds are unique to China,and this has given rise to worldwide interest.
