Catalogue: GRDC Final Reports
A disease control model for crown rot in Victoria and South Australia (SA) which provides crop management recommendations to reduce the build-up of Fusarium inoculum and avoid sowing into high disease risk situations... Crown rot is highly spatially variable, so intensive and extensive sampling programs were undertaken to assess the the reliability of results produced using current sampling protocols... Intensive stubble and soil sampling was used to assess the scale of spatial variability of crown rot and whether taking soil cores in a row crop was causing "spikes" in results...

The material is now at the F6 stage with selected lines showing promising levels of resistance in both field and seedling screens (up to 86% reduction in disease severity compared to EGA Bellaroi )... Significant field resistance to CR has been successfully transferred into durum wheats from hexaploid sources (up to 86% reduction in CR severity compared to EGA Bellaroi )... The project has also developed some lines which appear to have promising levels of resistance to FHB. Once backcrossed and incorporated into commercial varieties post-project this material should prove valuable in an integrated management system to control both CR and FHB...

In the project, we crossed a number of durum varieties to bread wheat lines, which are partially resistant to CR. Subsequent generations from these crosses were tested for their resistance to the disease in infected fields... The project has demonstrated that partial CR disease resistance present in hexaploid wheat lines can be transferred into durum wheats... The aim of the project was to transfer genetic loci linked to CR resistance in bread wheats, into durum wheats and to test the performance of derived lines in field trials...
