Growers do not have access to varieties with resistance to the key exotic pests and disease... The project will proceed in two phases... The project is about optimizing pesticide sprayapplications by: identifying spray technologies and spray settings with low risk of spraydrift, applying pesticides in accordance with latest knowledge about pest behaviour in response to pesticides andtherefore minimizes the risk of target pests developing resistance, and by using pesticides with documented efficacyagainst target pests...

Over the three-year course of the project, a total of 3,386 barley lines were evaluated in 24,155 assays... In 2006, the project was inundated with requests from barley breeders, and our facilities were used to capacity for this purpose throughout 2006, with 520 lines and a total of 12,480 plants assayed, and 61 lines (1,464 assays) into 2007... All seedling tests in this project were performed using a set of four specific isolates with characteristic pathotypes on the barley differential set...

Farmers beside a crop of Digalu wheat in Ethiopia, Africa, about 40,000 hectares of which was affected by a strain of rust unrelated to the Ug99 rust family in 2014 and 2015... The 2015 Borlaug Global Rust Initiative (BGRI) technical workshop hosted by the University of Sydney's Plant Breeding Institute attracted some 350 international scientists to Sydney in September to assess the rust threats to global wheat cropping... In 2015, the award recognised three Kenyan scientists who have spent the past eight years building a collaborative platform for rust research, which has allowed tens of thousands of wheat lines from around the world to be field tested for their response to the Ug99 rust races...

Medium and longer term benefits were developed from the isolation of the Adult Plant Resistance (APR) gene, Lr34, which showed that this gene encodes a protein not previously associated with rust resistance... The process of map based cloning of resistance genes from wheat steadily progressed during the project and continues to progress with increasing availability of cereal genome data and bacteria artificial chromosome (BAC) libraries made from important genotypes... The project provided information about the transfer of the stem rust resistance gene Rpg1 from barley to GM wheat...

A new cache of rust-resistance genes has been identified in durum wheat.. The new sources will increase diversity for rust resistance in modern varieties - By Dr Gio Braidotti.. Arthur Ernest Watkins may not have the posthumous name recognition of William Farrer but is belatedly leaving his mark on the world, thanks to a treasure trove of rust-resistance genes he left to wheat scientists and a modern world desperate to renew rust defences in wheat, especially against stem rust...
