Sugarcane is an important sugar crop with important economic value. The complexity of genetic background, theunclear origin and evolution and the lag of genomics research make it impossible to optimize the selection of parental materialsin sugarcane breeding, seriously restricting the development of sugarcane industry. In this paper, we reviews the research progress of the origin, systematic classification and evolution of sugarcane germplasm resources, the current situation ofconservation at home and abroad, as well as genomics in analyzing the genetic relationship and evolutionary history of sugar can especies and genera. The results will provide important references for the conservation, genetic diversity evaluation and industrial application & development of sugarcane germplasm resources.
