Implementing technologies and strategies to maintain resistance to sunflower rust

Abstract

This project proposes to implement resistance gene pyramiding strategies through close collaboration with Pacific
Seeds. These strategies have been developed by Department of Primary Industries and Fisheries (DPI&F) researchers
in two previous GRDC projects, DAQ356 and DAQ537. The gene pyramids will be incorporated into elite breeding
material using techniques and technologies developed by DPI&F. These include the use of DNA markers.
If successful, a range of elite lines/commercial hybrids containing strategic resistance gene pyramids will be available to growers. These lines will provide the industry with a directed strategy to manage the sunflower rust pathogen and reduce the risk of outbreaks of the disease.
