Research advances on genetic diversity in wild Cynodon dactylon germplasm

The genetic diversity of germplasm is the basis of survival, adaptation, evolution and the improvement of species. Wild populations of Cynodon dactylon, with various botanical characteristics and diversity, are an important gene pool for improvement and innovation of C.dactylon. This paper reviewed literatures on genetic diversity of wild C.dactylon from different levels including morphology, cytopathology, protein level, molecular marker techniques and breeding. At the same time, suggestions for the further study were proposed, in order to provide reference to the study on the genetic diversity of germplasm of wild C.dactylon.
