Abstract: With the rapid development of molecular markers, the technology is becoming more and more mature and has been an important means of studying forage germplasm resources. This article provides an overview of research progress on molecular markers, which used in yield, quality, stress resistance, insect resistance and other important traits of forage, analyze the problems in molecular markers with critical traits of forage and looks forward to the application prospect in order to provide references for further research on the forage germplasm resources.

Key words: Forage, Germplasm resources, Important traits, Molecular markers
