Study on Genetic Diversity and Germplasm Innovation of Subsect.Delavayanae of Peony
The Subsect.Delavayanae of peony is naturally distributed in China,and its rich genetic diversity is an important germplasm re-source to be developed to improve the flower color,change the plant shape,increase the floral fragrance and prolong the flowering period.In this study,we reviewed the genetic diversity of germplasm resources of the Subsect.Delavayanae of peony and the research progress of germplasm resource innovation,and elaborated the results of the study of the genetic diversity of Subsect.Delavayanae,meanwhile,this pa-per displayed the the current status of innovation and utilization of germplasm resources of Subsect.Delavayanae in China,in order to pro-vide reference for the development and utilization of the germplasm resources of the Subsect.Delavayanae of peony and the cultivation of new ornamental peony varieties with unique horticultural traits.
