Abstract (English):
The hundred-year period of development of woody plant selection in Voronezh is shown. Analyzing the directions and methods of forest selection, it is necessary to note the development of analytical and synthetic selection. A rationale is given for three types of selection in practical selection: mass selection or selection of ecotypes, group or population selection, individual selection. The study of the effectiveness of creating clonal and family seed plantations, introduced species, obtaining clone varieties, hybrid varieties and population varieties is shown. Using the cytological method, allotriploids of graying poplar, a hybrid of Canadian and balsam poplar (E.S.- 38), and triploids of pedunculate oak were identified. Induced mutants were obtained in balsam poplar, tetraploid balsam poplar. The creation of birch seed plantations from regenerants in vitro is proposed. The experience of creating plantation crops of poplar, silver birch and Karelian birch using in vitro biotechnology is analyzed.
