摘　　要：中国对虾(Fenneropenaeus chinensis)是我国海水养殖业中最具代表性的一项产业,优良种质和抗病力已成为对虾养殖业中迫切需要解决的问题。在遗传育种中若能筛选到与抗病、生长等数量性状紧密连锁的遗传标记,将为开展标记辅助育种工作和实现良种化奠定基础。对虾种质资源以及种群遗传学已成为研究热点,种群保护也已提到议事日程。这些研究工作的开展将为对虾良种选育提供理论依据,相信随着研究工作的继续深入,人们会更好、更有效地利用对虾资源。本文对目前已经在对虾遗传多样性和系统进化研究中进行应用的DNA标记技术方法进行分析总结,拟对今后其他物种开展相关工作提供借鉴。Farming of Fenneropenaeus chinensis is one of the most representatives in our marine aquaculture industry, the impending problems to resolve are the good germplasm and disease resistance. The screening of genetic markers linked with quantity traits like disease resistance and fast growth will help to develop marker assistant selection and select good breed. The research on shrimp germplasm resources and population genetics have become hot points, and population protection has already been scheduled. The developments of research will provide theory basis for shrimp selection, and with the development of research work people will make full use of shrimp resources. In the paper we analyze and conclude DNA molecular marker techniques used in shrimp genetic diversity and the molecular phylogeny, the main purpose is to use for reference for the relative research of other species.
