Project outputs will deliver new germplasm, associated DNA markers to resistance genes and associated genetic knowledge for adoption by commercial breeders to improve resistance. Yellow spot Achievements in combating YS were made across several facets of research through the national collaboration including: developing improved phenotyping methods identifying 19 new resistance genes developing fixed lines with stacked resistance genes and delivering them to commercial breeding companies identifying elite lines with broad spectrum resistance improving understanding of the virulence structure of the pathogen. Current research is focusing on elucidating the effects of individual resistance genes and gene combinations, evaluating effective resistance in multi-location and multiyear national trials, and developing resistance gene combination stocks in wheat relevant to northern, southern and western regions. Stagonospora nodorum blotch Significant progress has been made in SNB research to ascertain the genetic control of foliar and SNB resistance from different wheat origins and identification of DNA markers linked to genes. Single and combined genes are being deployed in Australian wheat varieties and evaluated for SNB response in WA production environments. Global wheat accessions are being evaluated to identify alternative genes for further improvement to SNB resistance. The project will deliver genetic products that enable commercial breeding companies to efficiently develop new varieties expressing improvements in SNB resistance. Grain growing will remain profitable when new wheat varieties are grown in paddocks under disease pressure. HIGHLIGHTS Pre-breeding research has resulted in genetic resources and associated genetic knowledge available for improving disease resistance in commercial wheat breeding. Fixed lines with stacked YS resistance genes express significantly higher resistance at both seedling and adult plant stages that is effective in various environments. Isogenic lines with different YS gene combinations will provide crucial information on the effects of individual genes and genes in various combinations within a similar background. The genetic control of SNB resistance is complex but significant advancements have been made to identify genes controlling foliar and glume resistance from different wheat origins. Genes with foliar and glume resistance to SNB deployed in Australian wheat are being evaluated for their effectiveness under disease pressure in WA production environments.
