Investigating multiple populations to gain an understanding of genotype x environment interaction information is common practice among modern tree breeders. Our study dealt with a single site; however, the trial represented multiple provenances, some of which were partially geographically isolated from the remainder of the population. No previous studies have investigated divergent evolution in E. bosistoana. While no clear differences existed between provenances within this experiment, further work is needed to identify where true provenance boundaries lie, as a better understanding of the genetic isolation of various sub populations of E. bosistoana may help explain the comparatively high heritabilities in this study.
Table 4 shows estimated expected gains under different selection regimes of the genetics within the trail. These gains are limited to the Woodville site, at age 21 months, using the testing procedures implemented here. The results show promise for an improved population to be used for future breeding efforts to improve both growth and wood properties.
