摘　　要：SSR是以几个碱基为基本单元的串联重复序列,广泛分布于真核生物基因组中。SSR信息量高,覆盖整个基因组,共显性遗传,多态性水平高,易用PCR分析,是一种非常有用的分子标记。对SSR的种类、研究进展、以及SSR在品种鉴定、基因作图和标记辅助育种等方面的研究应用现状作了简要概述。SSR (simple sequence repeats) is a simple, tandem repeated several nucleotide sequence motifs. SSR is widely distributed over the genome of eukaryote. SSR is very usually as genetic marker because it contains plenty of information, covers the whole genome, co-dominant heredity, and is easily detected by PCR. Types of SSR, progress in studies, and its application in identification of varieties, genetic mapping and marker-assisted selection were briefly reviewed in the paper.
