A new five-year cereal research project kicks off this month, aimed at boosting the resistance of durum wheat to the damaging pathogen, crown rot... Dr Anke Martin, University of Southern Queensland (USQ) research fellow (genetic solutions for cereal diseases) says durum wheat is very susceptible to crown rot and varieties with significant resistance have not been identified. ".. Crown rot in winter cereals is predominantly caused by Fusarium pseudograminearum and is recognised as a major disease constraint in many cereal growing regions in Australia," Dr Martin said. "..

" Durum Industry Development - Fast-tracking genetic solutions to crown rot (Phase 2) DAN00122 Start Date: 01/07/2008.. Commercial, near-release and reselected varieties should be evaluated for partial resistance and/or tolerance to crown rot using an inoculated versus uninoculated trial design across environments in northern New South Wales (NSW) to provide a more robust rating... A total of 972 lines representing various backcrosses between hexaploid resistance sources (Sumai 3, 2-49 and Sunco) and advanced durum breeding lines were evaluated for resistance (visual severity of infection) and tolerance (yield) under field conditions at Tamworth in 2010...

At the First International Crown Rot Workshop for Wheat Improvement held in Narrabri, NSW, the world's leading researchers on the disease met to discuss the progress of their research... The following is a summary of the global research position, as reported at the First International Crown Rot Workshop for Wheat Improvement held in October in Narrabri, NSW, in 2012... Research to date has focused on seed treatments with results showing some control of crown rot on wheat, with the whitehead rate declining significantly...

The background elite varieties to be used were selected by the wheat breeding companies and represent most of the bread wheat growing regions of Australia... The project has two components; one based in the University of Sydney will focus on wheats adapted to the Northern Region and will use a strategy of Marker Assisted Recurrent Selection (MARS)... The second component based in SARDI will focus on wheats adapted to southern and western Australia, will also use molecular markers but will focus on more conventional crossing strategies...

The project will continue to produce and release to breeding companies bread wheat lines with enhanced resistance to crown rot in better adapted backgrounds which may be used by commercial breeding companies to improve resistance to crown rot in released wheat cultivars... Dr Damian Herde of the Queensland Department of Agriculture, Fisheries and Forestry (DAFF) told workshop participants that there was a range of new material coming through breeding programs based on current commercial cultivars and recent additions.. Creating superior crown rot resistance in wheat is the aim of Queensland scientists at the Department of Agriculture, Fisheries and Forestry (DAFF), based at the Leslie Research Facility in Toowoomba...

Durum production in the southern region fell in the lead-up to this project... Samples from affected trials have been sent to a DNA laboratory for a quantitative assessment of fungal DNA. Irrespective of the mechanism, this germplasm appears to represent an improvement in field performance under disease pressure... Further research is required to complete this study and develop a more precise understanding of how the environment affects yellow pigment content...

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...
