Ecological and biological features and prospects of using Cotinus coggygria in breeding

Abstract

Due to the deterioration of the environmental situation, the requirements for the assortment of woody plants for landscaping territories for various purposes are constantly growing. To form a stable assortment of woody plants with the specified characteristics, it is necessary to use introduced species in the breeding process. The genetic collection of the VNIISPK Arboretum includes more than 310 species, forms and varieties of woody plants, including the Anacardiaceae family R.Br. All representatives of this family are introduced species, one of which is Cotinus coggygria. The purpose of the research is a comprehensive assessment of the ecological and biological features of Cotinus coggygria and its varieties to justify the use in breeding to obtain varieties with economically valuable traits in the conditions of the Central part of Russia. According to the research results, the most promising for use in breeding in order to obtain new varieties is C. coggygria cv. ‘Follis Purpureis’, which has a number of economically valuable features: winter hardiness, resistance to diseases and pests, complex of decorative qualities. C. coggygria cv. ‘Royal Purple’ can only be used as a source of resistance to diseases and pests and decorative coloring of leaves.
