Research Progress of Genetic Diversity of Forage Germplasm Resources in China

This paper was reviewed from the sides of study method(the level of grass morphology, cellular level,biochemical and molecular level)and the result of genetic diversity. It revealed our genetic diversity research status of forage germplasm resources and the main features of genetic diversity from different angles. At the same time, it found the lack of germplasm resources protection and genetic diversity research. At last, this paper also put forward the research direction of germplasm resources protection and genetic diversity study in the future.
