Abstract
The analysis of growth, seed production and pest resistance was carried out in 24-year old clones from5 latitudinal, 4 longitudinal and 5 altitudinal ecotypes of Siberian stone pine in the clone archive. Northern and highaltitudinal ecotypes had the weakest growth, weak or absent seed production, and were also severely damaged bypests. The local ecotype had average growth and reproduction rates. Southern and mid-eastern ecotypes had intensivevegetative growth, abundant seed production and absolute resistance to pests. They had the optimal combination of traitsfor plantation cultivation.
