Abstract: The results of assessing the resistance of 84 Scotch pine climatypes, growing in a provenance trial in a taiga zone in Middle Siberia, to pathogens are presented in this paper: pathogens of needle cast (Lophodermium pinastri Chev.), snow blight (Phacidium infestans Karst.), Cenangium diebak (Cenangium ferruginosum Fr.: Fr.) and rust (Cronartium flaccidum (Alb. et Schw.) Wint. and Peridermium pini (Pers.) Lew. et Kleb). The dynamics of the diseases caused by these pathogens are shown for a 30-year period. The authors found that Scotch pine resistance to the pathogens in the provenance trial depended both on ecological regime of the growing site and on the genetic peculiarities of the climatypes determined by their site of origin. Differences in the resistance of the same Scotch pine climatypes to the pathogens showed itself when growing them on different ecological backgrounds (on sandy soil - the bear berry pine forest type, and on dark-gray forest soil - the tall-herb pine forest type). Climatypes of “northern Lapponian” and “Siberian” pine subspecies are more tolerant to the pathogens.
