Quantitative trait loci (QTL) for acoustic wave velocity, as well as QTL previously identified for wood properties and growth, in three F1 families of Eucalyptus globulus. Each QTL is represented by an arbitrary 15 cM bar surrounding the QTL peak, where QTL maps within 7.5 cM of the end of a linkage group the end is truncated. ‘w’ and ‘v’ indicate QTL significant only in the Western Australian and Victorian trial sites, respectively. Candidate gene positions are indicated to the left of each LG, see Freeman et al. (2013) for more details
