- We looked at the patterns of differentiation at a set of phenotypic traits of Scots pine populations derived from different environmental conditions of the species distribution range in Poland. The growth traits were tested over 47 years at the provenance trial experiment in the Carpathians. The phenotypic differentiation of the populations was compared to diversity estimates at a set of ten nuclear microsatellite markers. Scots pine populations were highly differentiated concerning diameter at breast high, stand volume, stem straightness and crown width according to the prove− nance and climatic zones. At the same time a low genetic diversity for microsatellite markers and no evidence of population structure was found among proveniences. Local populations from the Carpathian Mountains had lower genetic variation and weaker growth compared to lowland provenances. Among the tested populations Scots pine from lowlands were characterized by the great growth potential and good adaptation to the severe climate of the Carpathians. Populations that showed high quantitative traits differentiation were genetically homogenous at the neutral loci. The results indicate that there are some regions in the genome under selection that drive species adaptive variation.
