XyloGene royalty fees
NZDFI has made significant progress in our tree breeding programme. Our selected germplasm has been tested in New Zealand environments with varying biotic and abiotic factors that influence tree growth. This ensures an advantage over unpedigreed provenance collections imported from Australia or those made from NZ stands planted with only one or two provenances. Our first-generation improved seed of mixed elite family origin will express outcrossing vigour and improved wood properties.
NZDFI’s genetically improved seedlots include:
- E. bosistoana 1st generation clonal seed orchard seedlots.
- E. globoidea 1st generation seedling seed orchards.
For the forest grower wanting to plant in 2026, these are the best genetics available and will produce increased productivity and quality gains at the end of rotation.
The different levels of genetic quality and the royalty fees are shown in the list below. Royalty fees contribute to continuing our R&D programme.
