Abstract
AnnotationAt present, in world science and practice, hybridization is considered to be one of the promising areas, which allows obtaining material with planned and properties. There was a need to use modern methods of mathematical processing to evaluate the prospects of some variants of crossing, dividing the total phenotypic variability into genetic and ecological. The results suggest the need to continue work on hybridization, taking into account the results obtained over the past 50 years of work on breeding, seed production and for crosses to use created from the offspring of plus trees in the region of maple, elm, which have been tested by natural selection in artificial and natural plantations of the South-East of the European part of Russia in recent decades. For reproduction of the obtained high-value breeding material to use breeding greenhouses and technology «in vitro». We believe that population selection can also be promising, and both natural and artificial populations can be used, in the biocenosis of which two or three seed generations of this species are present. At the final stage, it is necessary to create hybrid forest seed plantations from the material obtained.
