• a Marker interval on the consensus genetic map of loblolly pine. Markers that are underlined are common to the genetic maps of the populations compared. Markers not underlined denote interval boundaries inferred from homologous flanking markers.

• b * and ** represent chromosome-wide significance at P < 0.05 and 0.01, respectively, except for marker-trait associations detected by the two-QTL model (see footnote d below).

• c Percentage of the phenotypic variance explained by a QTL.

• d A QTL detected only by the two-QTL model in the verification population with significance levels as in Sewell et al. (2000): *, 0.01 > P > 0.005; **, P < 0.005. PVE refers in this case to that explained by the pair of QTL detected.

• e QTL detected by the two-QTL model in both the detection and verification populations.
