Macadamia regional variety trials series 4 (MC17006)
What’s it all about?
This investment is continuing to evaluate the performance of new and emerging macadamia varieties, and will feed information on these varieties through to industry.
The information it generates will ultimately help guide growers in making decisions about new varieties for orchard expansion, development and possible replanting in key growing regions. The varieties it helps commercialise will have benefits including higher and more consistent production of high-quality kernel, resulting in a more profitable and prosperous industry in Australia, based on internationally competitive exports
This trial work carries on from earlier iterations of the regional variety trial series, with the previous project Macadamia regional variety trials – series 3, phase 2 (MC11001) identifying four new varieties for commercial release.
To learn more about the macadamia varieties produced by this investment, including information on how to access them, head to the Macadamia Innovation website.
This project is tasked with testing 23 new superior clones from seedling populations produced by the National Macadamia Breeding Project.
Locations for two comprehensive testing sites have been confirmed at Bundaberg and six supplementary grower blocks from the Northern Rivers region of NSW to Rockhampton in central Queensland.
At the comprehensive sites, a full range of data will be collected, with the supplementary trials to be a complementary data collection resource and useful tool for assessing localised performance and providing budwood supply for commercialised cultivars.
Forty dwarf rootstocks will be planted at a Bundaberg site to test compatibility, tree performance and susceptibility to abnormal vertical growth.
In recent months, the project completed harvest of the 2019 Regional Variety Trials, with samples sent for analysis and nursery propagation started using two groups of cultivars. A further round of cincturing to be completed in March for May grafting.
This project is a strategic levy investment in the Hort Innovation Macadamia Fund
