Most productive populations of Siberian stone pine trees were revealed as a result of many years study of the selection structure of the Siberian stone pine forests in the Republic of Altai. Based on the analysis of archive materials and ground inventory of the selection and genetic objects, the information about their quantity and preservation is provided. Currently, in the Republic of Altai, 320 elite trees have beenregistered, and on this basis 60.9 ha of forest seed plantations and 13.7 ha clone archives have been established. In the period of 2005-2014, the number of elite trees was reduced from 438 to 320. Experimental elite tree crops not presented. According to the inventory, as of 2014, at forest seed plantations and at the archives of clones grow 4.837 grafted trees of 282 clones, 139 of whichare progenies of the elite trees, selected for seed production, 124 - for resin production, and 19 - for the productivity and quality of stem wood. All clonal facilities are concentrated on breeding nursery of the Teletskoe forestry district area of ​​about 75 ha. Unique clonal objects of the Siberian stone pine in Teletskoe forestry district play a crucial role in the preservation, study and rational use of the gene pool of this tree species and require continuous monitoring of their condition and protection. Visual forest pathology inspections and molecular genetic diagnostics revealed that on clonal plantations of the Siberian stone pine, progressive needle disease developed, caused by new for Western Siberia an extremely dangerous pathogen - Dothistroma septosporum (Dorog.) M. Morelet. In this connection it is necessary to conduct appropriate sanitary measures and to carry out additional studies of population genetic features and pathways for this pathogen. The priority activities have been outlined to further development of the unified genetic and breeding complex of the Siberian stone pine in the Republic of Altai.
