In the given work we study the growth characteristics of hybrids pine ordinary in 1 to 3 years of age, resulting in a controlled crossing with various ecotypes. Found that the differences among hybrids in height were more pronounced in the 1-year old, and when the plants age of 3 years, there smoothing growth rate. Better control (40.8 cm) in 3-years of age are growing hybrids from crosses involving aimed ecotypes Estonia (58.8 cm) and Volyn (57.4 cm) of origin. In other cases crosses hybrids pine ordinary grow at or better than the control (41.6–51.6 cm), but the differences were not statistically significant.
