Scatterplot of metadata concerning height prediction accuracy, from various sources of GS studies [19,21–30] in forestry of conifer species.
Filled points represent studies using full-sib populations; empty points represent studies using half-sib populations; empty points with crosses represent studies using full and half-sib populations. Point diameter is a function of sample size. Marker density was calculated based on genetic map lengths estimated in the following studies: Pinus taeda [31], Picea glauca [32], Picea glauca x engelmannii (based on white spruce data) [32–34], Pinus pinaster [35], Picea mariana [36], Picea abies [37].

Effect of marker density on RR-BLUP prediction accuracy for multi-site data for height and wood resistance, with ABLUP for comparison, for: a) Douglas-fir (HT at 35 years, WDres at 38 years), and b) Interior spruce (HT at 38 years, WDX-ray at 38 years).
