Mating system analysis in a central and Northern European population of picea abies

Mating system and genetic variability were studied in a southern and a northern population of Picea abies, in Czechoslovakia and Finland. Both populations had considerable genetic variability, with expected heterozygosities of 0.17 and 0.23, respectively, at nine loci. The two distant populations were more differentiated (Gst = 0.12) than has been found in studies on Scandinavian Picea abies. Both populations had a considerable degree of partial selfing, with estimates of outcrossing of 0.83 and 0.74 in the populations from Czechoslovakia and Finland, respectively.
