Summary
1. Work towards an agreed product profile. 2. Generate a pipeline of new cultivars with a target release date commencing 2023. 3. A cultivar release will be determined to have occurred when a pack of seeds (minimum of 200) or tray of 10 clones is passed from the breeder to the propagator. 4. Maximise genetic gains by releasing cultivars as clones or full sib families from annual testing and selection in an intensively managed elite population. 5. Improve a broadly based main breeding population in discrete generations by open pollination. This will act as a resource to enable progressive infusion of new genes (alleles) into the elite population, and as a backup resource for supplying a next generation of open pollinated seed cultivars. 6. Generate controlled biparental crosses in an elite population to maximise gain per year. 7. Secure, document and curate metadata describing TTBP I physical resources. This will underpin management of the CropStoreDB for Tea Tree integrated database that will capture all relevant cumulative data and metadata in common formats. 8. Establish secure germplasm resource collections as duplicated seed repository and living collection(s), with potential for live duplication on SCU land in Lismore, and possible duplication on producers’ land holdings. 9. Establish an open pollinated progeny trial, which if required, may be converted to an orchard to supply a next generation open pollinated seedling cultivar in 2026. 10. Elite genotypes from TTBP I will be captured by cloning for use in a controlled pollination orchard, and archived in a clone bank.
