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.

Highlights

In the context of constantly developing industry and urbanization, cities have become centers that provoke environmental changes on various scales
The weather regime of Central Russia, which largely depends on the movement of air masses coming mainly from the Atlantic and the Arctic, or, less often, from Western Siberia and Kazakhstan, is characterized by variability of atmospheric circulation in some years, which leads to significant deviations of temperature and precipitation values from the average annual data [17]
A comprehensive assessment of the ecological and biological features of Cotinus coggygria and its varieties allowed to conclude that C. coggygria cv

Summary

Introduction

In the context of constantly developing industry and urbanization, cities have become centers that provoke environmental changes on various scales. The material needs of production and humans change land use and vegetation cover, biological diversity and hydraulic systems at the local and regional levels, and waste disposal affects local and global biogeochemical cycles and climate. The state of ecology requires solving the problems of sustainable development of an increasingly urbanized world [1]. The development of landscape design in cities and villages as a means of optimizing the human environment is directly related to the problem of expanding a sustainable and longlasting assortment of ornamental plants. In urbanized landscapes, trees and shrubs are often exposed to a high level of stress (shading, drought, air and soil pollution), which shortens their life expectancy and reduces their decorative value. Plants that are familiar to us often lose the ability to perform their functions [2,3,4]
