The article presents data on the quantitative trait "growth in height", the importance of studying such traits in woody plants, and models for implementing genetic information to the phenotype level. Trees of the same origin were grown at different times and in different edaphic and ecological conditions - in leached chernozem and gray forest soils. Morphological indices of trees were analyzed, and it was noted that downy birch and its hybrid grow better on nutrient-poorer (gray forest) soil. In addition, some polyploid introduced species (Bet. ulmifolia, hexaploid, 2n=6x=84) also grow better on gray forest soils. Possible causes of the observed growth processes are discussed.
