The University of Sydney will join Intergrain and S&W Seed Company in a new study of oat rust.
The Australian Research Council has granted the researchers $928,845 to carry out the research into crown rust, a fungal pathogen affecting Australian oat production.
World-renowned crop disease expert Professor Robert Park will lead the research team, working with two Australian oat-breeding companies
Intergrain, Bibra Lake, WA, will focus on hay and milling oats, and S&W Seed Australia, Wingfield, SA, will look at grazing oats for livestock.
Professor Park said the Australian oat industry had been plagued by recurring epidemics of the destructive disease crown rust ever since oat cultivation began.
The diseases occurs globally and is considered the most important disease limiting oat production worldwide.
"Crown rust causes severe damage to oat crops in Australia and, due to ongoing losses of important resistance genes since the early 1990s, it has become an intractable constraint to oat production. Loss in grain yield can be as high as 50 per cent in susceptible varieties," Professor Park said.

Australia produces three oat types: grazing for the meat and livestock industries; hay for animal consumption; and milling for human or animal consumption.
Many grazing oat varieties with genetic resistance to crown rust were released in Australia from 1990-2020.
Although resistant when first deployed, new rust strains emerged soon after rendering all these varieties highly susceptible to the fungal disease.
"Our project aims to reduce the impact of crown rust in Australian oat production. It will deliver robust genetic resistance to crown rust to all Australian oat growers."
The University of Sydney team will work with researchers at Murdoch University and the Leibniz Institute of Plant Genetics & Crop Plant Research,Germany.
"The work with these colleagues will provide vital genetic expertise," Professor Park said.
"The Leibniz Institute and Murdoch University are part of a global effort that is sequencing and characterising the oat genome.
"This work will accelerate our efforts to deliver oats with improved rust resistance to oat growers."
"We expect the project will also lead to responsible stewardship of broadly effective crown rust resistance in all types of oat production in Australia, increasing grower profitability, reducing reliance on fungicides and underpinning planned growth in our export oat market."
