The importance, historical aspects and results of the study of Scotch pine plantations created from seeds of ecotypes of different geographical origin are highlighted. Using the scale of assessment of ecological-geographical plantations, 10 ecotypes of pine were analyzed by quantitative and qualitative indicators. The largest biometric indicators are characterized by plantations grown from seeds of local origin. Pine of local origin according the growth and resistance to the action of negative factors dominated by plantations created from the seeds of other regions. According to the augmented scale of assessing the prospects for using ecologic-geographical plantations, it was found that the sum of points in 10 ecotypes varied from 6 to 20. With increasing distances of places of origin to the northeast and east, the productivity and quality of tree stands deteriorates. In most groups, the best options were the offspring of the local pine, the Left Bank and Right Bank Forest-Steppe, with a score of 19-20 points. The ecotypes of steppe origin had the best preservation and in the future they will be most resistant to adverse natural phenomena and climate change.
