Saccharum spontaneum L. is one of the original parents of cultivated sugarcane varieties and important to sugarcane cross-breeding. Meanwhile, it is being tested for the development of bioenergy cultivars. Recently, molecular marker technique has been applied widely in studies of S. spontaneum L. such as determination of genetic diversity, identification and classification of the germplasm, analysis of phylogenetic relationships, construction of genetic linkage map and so on. This paper reviewed the application progress of molecular marker in S. spontaneum L., also anslyzed the existing problems and discussed its prospective utilization in future study.
