Executive summary

The second (Avery) of three E. globoidea breeding trials has been phenotyped for heartwood properties. The results are comparable to the assessment of the previous E. globoidea trial at Atkinson. The data has been loaded into the NZDFI Kathmandoo database.

The work has shown that heartwood traits in this E. globoidea trial were under genetic control and families with more and better heartwood have been identified. The best performing families had twice as much heartwood and extractives as the least performing families. As this is one of three trials of this breeding population the best selection will be possible once all three trials have been assessed and analysed.

The third and last trial (JNL Ngaumu) has been cored in June 2021 and is awaiting heartwood quality measurements (NIR). Once that data is available all three trials can be analysed for GxE effects and more confident statements on superior families and their performance can be made.
