Micro-satellite markers are valuable PCR-based molecular markers. Compared with other molecular markers, micro-satellite markers have additional advantages such as high polymorphism and good repetitive. They are also technically easy and inexpensive in use. In this paper the principle and method of micro-satellite technique and its application in rice were present.

微卫星(M icrosatellite)也称简单序列重复(Sim pleSequence R epeats,SSR)或短串联重复(ShortTandom R epeat,STR),是指一类由几个核苷酸(一般为2~4个核苷酸)为基本重复单位(基元)构成的串联重复序列[1,2]。这些串联重复序列由于基元的重复次数不同而形成的多态性称为简单序?
