This article focuses on the relationship of endophyte with its host and the progress of breeding techniques. The method is literature review. It mainly reviews that endophyte with its host on growth, its role in promoting stress resistance, traditional breeding technique, protoplast technique and molecular breeding technique. Endophyte can enhance the ecological adaptability of the host, it can not only increase the total plant biomass, seed germination, seedling survival and other aspects, but also improve host resistance and so on. As long - term co - evolution with each other, they form a mutually beneficial symbiotic relationship. In recent years, using molecular engineering technique, it can make good results, but the traditional methods of physical and chemical mutagenesis are still very important. The ge- netic sequence of endophyte is complicated, so it is still very difficult in the molecular breeding technique. It is believed that molecular breeding technique will become the focus of study, but the relevant results achieved in the application has not been reported until now. Finally, the existing problems on endophyte are summarized in current research.
