This research indicates that it may be possible to select cultivars of Backhousia citriodora (lemon myrtle) with greater myrtle rust resistance than the moderately to highly susceptible cultivars that are currently in use by the native food, essential oil and horticultural industries in Australia.
It is well recognised that different research approaches will be required to address problems faced by both industries and the environment as we respond to the management of myrtle rust. The presence of the gene-pool planting of lemon myrtle at Beerburrum, in South-east Queensland where myrtle rust is currently prevalent provided an ideal opportunity to observe, monitor and select for the variable responses of this important native food species to myrtle rust. This research has provided specific insights into resistance breeding within the species and has also provided learnings in relation to other disease management options for this crop.
