  • Mixed linear models included a factor identifying clones from west or east of the Mississippi Valley, a potential cause of population structure. ewsg, earlywood specific gravity; lw, percentage of latewood; ewmfa, earlywood microfibril angle. Only SNP per-trait associations with FDR Q-values <0.10 are shown. FDR Q-values ≤0.05 are in italics.
