^aThe number of genotyped individuals in each genetic cluster using for population structure
BB budburst stage, Height tree height, DBH diameter at breast height, FD frost damage, WD wood density, MFA microfibril angle, WS wood stiffness
The different genetic clusters are Alpine, ALP; central and southern Sweden, CSE; Central Europe, CEU; Fennoscandia, NFE; Northern Poland, NPL; Carpathian, ROM; and Russia-Baltic, Rus-Bal
^bThe 914 individuals were genotyped by a recently developed Picea abies SNP array [20]
