The variability of the Siberian cedar in terms of the intensity of growth and yield, growing on the site “Continuation of the geoschool” in the suburban area of Krasnoyarsk, is considered. The trees were grown from the seeds of the Tanzybei (Krasnoyarsk Territory) and the Altai (Altai Republic) populations. The layout is 4×4 m. The height, diameter of the trunk, crown, and the number of cones on the tree have been determined. It was found that the average height of trees of different geographical origin is 11.5 and 12.9 m, the trunk diameter is 24.6 and 25.2 cm, respectively. The level of variability of growth indicators is medium and high. The number of cones on the tree ranged from 10 to 159. Trees were selected that differ in growth intensity and yield for the cultivation of selective planting material.
