摘　　要：桃(Prunus persica[L.]Batsch)是蔷薇科重要的核果类果树,适应性强,栽培范围广,果实口感好,深受消费者喜欢。提高桃果实品质及增加抗病、抗虫性一直是桃遗传育种者关注的焦点。文章对近年来桃遗传分子标记连锁图谱和物理图谱构建、分子标记开发应用、全基因组和转录组测序工作中所取得的最新成果进行综述,同时阐述了高密度SNP芯片标记技术在桃以及其它作物上所开展的全基因组关联分析应用实例,为桃进一步开展全基因组关联分析,挖掘目标性状QTLs以及高效育种选择标记提供理论基础。Peach （Prunuspersica （L.） Batsch） is one of the most predominant stone fruits in Rosaceae family. The broad climate adaption, diverse cultivation region and good fruit taste make it one of the favorate fruits by consumers. Improving fruit quality and enhancing disease/pest resistance are always a focus for peach genetists and breeders to follow with inter- ests. This paper reviews the main achievements on linkage map and physical map construction, development of various molecular markers, whole genome sequencing and transcriptome sequencing for peach in recent years, and also elaborates the applications of genome wide association study （GWAS） with high density SNP markers in peach and other plant crops. This review also provides a theoretical basis for GWAS analysis in the future study to identify high efficient markers of targeted traits for peach.
