They have been applied in many aspects of genome re- search. This paper has clarified the theories and characteristics of SSR as well as ISSR. The authers also sum- marized their applications in geneticpolymorphisim andgeneticrelationship, establishment of DN fingerprinting pool, construction of geneticmap, genelocalization and marker- aided selection. Thetwo methods of DN ec- ular marker open up broad prospects for the studies of plant genetics and breeding.
