Highly improved tea tree varieties to maximise profit

Summary

The Australian tea tree industry currently faces the risk of significant overseas competition developing as the oil price improves. Increasing onfarm profitability through the release of new varieties with greater yields and quality must be the primary goal of the industry to increase the economic viability and competitiveness of Australian producers.

Objective Summary

To release highly improved seed and clones to maximize the production of high quality oil and plantation profitability. Progressive genetic improvement is achieved through (i) the ongoing development of established seed orchards (CSO1, CSO2, SSO2, SSO2p) using a recurrent breeding strategy (ii) the establishment of new orchards (SSO3 and SSO3p) to ensure the longterm advancement of genetic gain (iii) the establishment of new progeny, yield and clonal trials to provide data for orchard culling and selections for cloning and to quantify yield gains from orchard progeny and elite clones (iv) investigating the insect resistance of specific genotypes, with a view to reducing insecticide use (v) investigating the frost tolerance and survivability of specific genotypes, with a view to reducing losses to climatic extremes.
