^aQTL LOD peak position
^bClosest marker to QTL LOD peak
^cGenome wide significance * = P < 0.05, ** = P < 0.01. The remaining QTL were significant at the suggestive level (chromosome-wide type I error rate < 0.05)
^dThe percent variation explained at each QTL peak
^eKruskal-Wallis significance at the closest marker (ie adjacent marker) to each QTL peak. * P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001
^fPositonal support for QTL from those found in the FWK population, all of which were significant at the suggestive level. In each case, the trait for which the supporting QTL was found is shown, (#) indicates average distance to the closest shared marker to each of the QTL in each map
^fSilviscan traits are an average from two measurements: tree-rings 1–5 and tree-rings 6–10
