摘　　要：单核苷酸多态性(Single nucleotide polymorphism,SNP)作为第三代分子标记,具有位点丰富、代表性强和遗传稳定等特点,已成为分子标记研究领域的焦点。本研究综述了SNP特点、检测方法及其在肉牛生长发育性状、繁殖性状、胴体与肉质性状的应用,作为分子标记辅助选择的候选基因,加快了肉牛育种进程。Single nucleotide polymorphisms（SNP）,as a third generation molecular marker,has many characteristics,such as rich sites,strong representation and genetic stability,it had became the focus of molecular markers related fields.This paper reviewed the characteristics and detection methods of SNP and its application in beef cattle ＇ s growth traits,reproductive traits,carcass and meat quality traits,as the candidate gene for molecular marker assisted selection,to accelerate the speed of beef cattle breeding.
