\section{Conclusion}  The modified rapid screening test for growth strain captured population variability in \textit{Eucalyptus bosistoana} which is under genetic control.  Narrow sense heritability of growth-strainin \textit{Eucalyptus bosistoana}  was estimated to be 0.63, with a 0.28--0.98 95\% credible interval. This suggests there is a sufficient level of genetic control for that  a breeding programme to could  effectively reduce growth-strain in the population. Heritabilities for wood density, stem diameter, volumetric shrinkage, acoustic velocity and wood stiffness are also presented. All of them are within the range described in previous publications. A strong, unfavourable correlation between growth strain and stiffness was found, indicating a trade-off indicates that tree selection  will have to be considered deal with a trade-off between those traits  when breeding for overall wood quality in \textit{E. bosistoana}. This pilot study demonstrated the feasibility of implementing rapid growth-strain screening at a speed and reliability that would scale up to an operational breeding programme.
