A. A. Ivanov | M. V. Vasilyeva | I. N. Anisimova | R. S. Rakhmangulov
The genus Paeonia L. includes both popular ornamental and medicinal plants with a rich history of cultivation and breeding. Breeding is an important process of increasing the diversity of the assortment and creating new cultivars of peonies with various economically important characteristics, such as the shape and color of flowers, different flowering periods and resistance to diseases and abiotic stressors. The main methods used in the breeding of peonies are traditional methods, including intraspecific, interspecific and intersectional hybridization, however, such factors as a long reproduction cycle and the complexity of the breeding process limit the possibilities for good progress in this work. The application of methods of biotechnology and molecular genetics make the breeding process more efficient. The use of germplasm resources and hybridization will accelerate the process of creating new cultivars not only with various decorative features, but also those with high adaptability to biotic and abiotic factors and resistance to phytopathogens and diseases. This review highlights the history of domestic and foreign breeding, modern trends and methodology of peony breeding. Information is provided on the achievements and limitations that exist in the field of molecular biological study of peonies.
