Gary Baker had been the Project Officer of the Tea Tree Breeding Project since it commenced in 1993. The project has progressively released seed from improved breeding lines to growers since 1997. In less than a decade of breeding and selection and release of seed to industry, oil yields have increased from 148 kg/ha to approximately 250 kg/ha, equivalent to a 70% yield improvement. Desirable changes in oil quality traits that enhance market access have also been achieved in parallel with the yield increase.
Gary continues to work on releasing improved tea tree germplasm.
