Abstract: As a new hot spot in plant biotechnology,cell suspension culture technology can be used not only for protoplast isolation,culture and hybridization,but also for genetic transformation and obtaining transgenic plants using embryonic cell suspension lines as recipient materials.This study focused on the selection and breeding of new Chinese rose varieties,in order to provide excellent recipient materials for Chinese rose transgenic experiments in a new way.Theoretical references were provided for the establishment of stable cell suspension system and genetic improvement of moon season,and the prospect of the application of cell suspension culture in moon season was also presented.
