The purpose of the work is definition of Scots pine Pinus sylvestris L. seed transfer range in Siberia on the basis of growth success of 40 year-old provenance trial established in Boguchany forestry of Krasnoyarsk region. In the provenance trial 83 climatic ecotypes are studied in different growth conditions. More than 40 % of climatic ecotypes originally are from Siberia. Long-term observations of complex of traits (survival, height and diameter growth, stock of timber, plant pathology conditions and form of tree trunk) in the provenance trial allowed making analysis of rank stability of climatic ecotypes. Analysis of climatype stability in selection indexes was conducted in different ecological and climatic conditions. Perspective climatypes within each experimental plot were revealed and differences between plots were shown. Average index of complex of traits was obtained. This index is a final assessment of growth success at the present age and the basis of comparative analysis of similarity and difference of climatypes. Recommendations of seed transfer and highlight of forest regions were suggested on the basis of comparative analysis. Seed transfer in latitudinal and longitudinal directions are recommended in definite limits, direction of world’s sides must be taken into account during creation of forest plantations. Five forest regions are recommended for practical usage within definition of forest seed zoning of Scots pine and for forest stations involved in growing of forest plantations on the territories of Krasnoyarsk region, Khakasia, Tuva and Irkutsk region instead of eleven active in present time, their borders are presented in the map in present paper.
