Results and Discussion
While the study was larger than preceding attempts, the sample number
was still small when considering heritability calculations. The paucity
of data resulted in wide 95% credible intervals (Table \ref{559243}), which
require more samples to tighten. The heritability indicates that growth
strain can be influenced by breeding, and are in line with the 0.32
reported by \cite{Murphy2005}, but are significantly higher than the
0.02 value reported by \cite{Naranjo2012}. Density, diameter at age
two (growth), volumetric shrinkage, acoustic velocity and stiffness all
have significantly large heritability, suggesting that breeding for
these traits is achievable. The heritabilities are similar to those
reported for other eucalypt species \cite{Hung_2014,Hein2012,Blackburn2014,Hamilton2008}.
