A provenance test of 49 seed sources of Scots pine (Pinus sylvestris L.) from eastern Europe, Russia, and Siberia was established in two plantations in north-central North Dakota. After 22 years, trees from seed sources within the region bounded by 20o to 57o east longitude and 50o to 58o north latitude were taller, and larger in diameter, and had denser crown and greener winter foliage. Total height at age 5 and age 10 was highly correlated with total height at age 22, indicating that selection at an early age (5-10 years) may be possible in Scots pine breeding programs.
Keywords: windbreaks, shelterbelts, seed sources, varieties, selection, crown density, winter foliage color, geographic variation, (Pinus sylvestris L.)
