Accuracy of cross-population GS prediction models (indicating their respective correlations (Y-axis)) for seven growth and wood quality traits for interior spruce. Sites are Prince George Tree Improvement Station (PGTIS), Quesnel, and Aleza lake. Traits are HT: height in m; DBH: diameter at breast height in cm; VOL: stem volume in m3; VDir: acoustic velocity in km/s; WDRes: resistance to drilling; WDX-ray: wood density in kg/m3 using X-ray densitometry; MoEd: dynamic modulus of elasticity. Dash and solid lines represent Type B correlation and prediction accuracy, respectively.
