mapping population

Catalogue: GRDC Final Reports
While the approach has enabled population structure to be accounted for, it perhaps imposes a limitation on the effectiveness of using this approach in cereals within breeding programs... The result of the LD study was to confirm that significant levels of LD could be detected within germplasm collections, and that this LD extended over sufficient distance that it could be effectively assayed using currently available marker technologies such as SSRs and DArT... While the methodology used in performing this analysis is radically different to that used in conventional QTL mapping in bi-parental crosses, the fact that identical QTL locations have been derived lends support to the conclusion that association mapping is a viable approach in these clearly defined populations...

Studies within the project have shown that some of the newly identified slow rusting genes have pleiotropic effects on multiple diseases... In the first phase of this project, this partnership led to the cloning of the first adult plant resistance gene, Lr34/Yr18/Pm38 and the development of a gene-based molecular marker that is routinely being used by many breeding programs worldwide... In 2012, Australian wheat, durum and triticale varieties were also evaluated for stripe rust, as well as for leaf rust in Mexico with prevalent races that constitute an important threat to wheat production if introduced to Australia...

Dr Jack Christopher from Queensland DAFF discusses stay green wheat at a field study day in Gatton on the Darling Downs, Queensland... The event gave researchers, plant breeders, agronomists and growers the opportunity to see firsthand the research being carried out in the region... Researchers from the Queensland Alliance for Agriculture and Food Innovation (QAAFI), the University of Queensland, and the Queensland Department of Agriculture, Fisheries and Forestry (DAFF) talked about their work on pre-breeding, disease resistance and frost tolerance in wheat and barley...
