The paper deals with evaluation of the lodgepole pine research provenance plot in the pine site conditions in Trebon (Southern Bohemia, Czech Republic) at the age of 34 years. Based on the evaluation of specific quantitative and qualitative traits (height, DBH, stem volume, tree stock, mortality, defoliation, stem form and height of stem forking, branch thickness, and bark type), provenances were assessed in terms of their production capacity and utilization on extremely dry sandy soils. The lowest defoliation (20-25 %) has been recorded in the case of provenances No. 2089 Manzanita, No. 2235 Calling Lake and No. 1902 Mile 86, most others did not exceed a level of 50 %, but four provenances had a high needle loss (71-79 %). From the volume production point of view, the provenance No. 2089 Manzanita (P. c. subsp. contorta) from the Oregon coast and No. 2091 Mount Hood (P. c. subsp. latifolia) from Oregon Cascades, demonstrated their high production ability. The best-growing provenance No. 2089 Manzanita corresponds through its growth characteristics to the fourth relative site class of domestic Scots pine, which confirms that proper selection can find suitable provenances that can fulfill the production function even in poor and dry site conditions.
