Improving resistance to stagonospora nodorum blotch (SNB) in wheat - DAW00248 (2015 - 2020)

This project, funded by Grains Research and Development Corporation (GRDC), will deploy existing and new sources of resistance in Australian wheat varieties and validate effectiveness of single and combined genes for expressing enhanced SNB resistance in Australian wheat production environments.

Previous GRDC investments through projects DAW00089 and DAW00126 made significant advances in identifying novel sources of resistance to SNB in flag leaf and glumes. Knowledge and resources to manipulate the genetic control of adult plant resistance can be used to develop appropriate SNB resistance in wheat varieties. Therefore, this project (DAW00248 commenced July 2015, completing June 2020) will deploy and validate effectiveness of combining different genes from existing and new genetic sources that will enhance SNB resistance in Australian wheat varieties.

Project aims

  • Identify existing and new sources of SNB resistance that can be used in germplasm development and commercial breeding.
  • Deploy existing and new resistance genes from global wheat accessions into Australian cultivars and identify single or gene combinations that will make significant improvements in flag leaf and glume resistance.
  • Evaluate and identify wheat germplasm with single or combined genes that express improved SNB resistance in Australian wheat production environments.
