Abstract. When growing pine plantations in the desert in recent years using a variety of introduced species of pine (Crimea, yellow, Banks) which are insufficiently studied in these conditions and require studies of their adaptive capacity. The article is the result of research conducted by the authors in 2004-2015. The collection, analysis of experimental materials, and field experiments were carried out. The article summarizes the authors’ long-term research on the introduction of different types of pines. They generalized the data on growth, conditions, reproductive capacity of pine species (Pinus) in natural and artificial plantations for protective afforestation in arid conditions of the Lower Volga region. The experience in breeding pine in the desert proves the prospects of using natural selection to create sustainable biogeocenosis with a wide genetic diversity. A comparative study of pines introduced under the desert conditions is a perspective Crimean pines and yellow, not inferior to the growth of Scotch pine.

According to the research, the article reveals the benefits of the Crimean and yellow pines of Scots pine on a number of factors: drought tolerance, resistance to diseases and pests. Consequently, these pine trees are to be used for afforestation in the harsh conditions of the desert.
