Growth and health state of spruce clones in two ortets mixture and in several clone plantings in various conditions have been compared. Experiments dealt with Norway spruce (Picea abies (L.) Karst.) originated from selected populations in Krkonoše Mts. Relations between growth of ortets and their vegetative propagated clones have been evaluated aimed to find the possibility of selection the resistant clones in growing ortets and clone plantations in mountain conditions. The fact that altitude of ortets did not influence growth of their clones confirms the assumption about efficiency of establishment of parent tree plantings in favourable conditions of lower altitudes. Ortets there grow quickly and soon get strong vitally cuttings.
