Development of molecular markers for Fusarium wilt resistance in banana (BA17006)
What’s it all about?
Fusarium wilt – particularly that caused by Tropical Race 4 (TR4) of the fusarium pathogen – threatens the viability of commercial banana production in Australia, and worldwide. Once present in a plantation, the fungus persists in the soil or in alternative hosts and cannot be eradicated, and there are no known chemical controls. This leaves genetic resistance as the only viable option for Fusarium control.
To help in the identification of disease-resistant banana varieties, this investment began in 2019 to develop molecular markers that are associated with different sources of genetic resistance to Fusarium wilt in banana. Once available, these molecular markers will allow screening and selection of resistant germplasm for introduction into Australia.
By nature, project activities are largely technical, so look for outcomes to be reported at the end of the work’s run or as any significant developments are made.
This project is a strategic levy investment in the Hort Innovation Banana Fund
