Ms Ganesalingam applied biometric techniques to analyse seven years of national canola blackleg resistance trial data, providing what her supervisor at the University of Western Australia, Professor Wallace Cowling, describes as a "remarkable improvement" in the stability of the analysis... With the long-term analysis over seven years, Aanandini found that some varieties have stable variety resistance ratings," says Professor Cowling. ".. By using the latest MET analysis, Aanandini has shown that large GxE interactions occur in canola blackleg disease across sites over the years but this GxE can be modelled to improve the analysis and thereby improve our understanding of blackleg resistance in canola varieties," she says.

Canola plays a crucial role in Australian agriculture as a cash crop and through its rotational benefits to subsequent cereal crops... Blackleg is managed by breeding for resistance and crop management practices that minimize stubble inoculum... The blackleg fungus is adept at overcoming cultivar resistance leaving many crops vulnerable to significant yield loss...

Author : Sharon Watt Oilseeds disease authority Dr Steve Marcroft says severe early blackleg disease infection in 2016 could be attributed to the combination of three factors - wet weather, breakdown of cultivar resistance and the onset of fungicide resistance... A combination of factors has led to severe early infection of blackleg disease in this year's canola crops in southern Australia (South Australia, Victoria and southern New South Wales)... "Normally with blackleg we tell farmers to monitor their crops at end of season to see how much stem canker they have - it's quite unusual for the disease to be striking young crops so severely at this time of the year," said Dr Marcroft, whose research is supported by the Grains Research and Development Corporation (GRDC)...

A better understanding of the canola genome should deliver a major advance in improved varieties, including the eventual development of blackleg resistance.. The first project has delivered some 500 DNA markers tagging locations in the canola genome controlling blackleg resistance under Australian growing conditions... "The results confirm earlier observations that blackleg resistance sources coming out of Canada and France are not really working in Australia," Dr Cogan says...

The fungal disease 'blackleg' is the most severe disease of canola in Australia, causing yield loss and in some circumstances total crop failure... Blackleg is primarily controlled by breeding disease resistance into canola cultivars prior to release to industry... The project will assess the level of blackleg resistance in all canola cultivars enabling growers to select a cultivar that is suitable for their farming system and climatic region...

In summary, it could be argued that none of the currently available preemergence herbicides have the required stability in efficacy to become viable alternatives to postemergence group A or imidazolinone herbicides... Overall, 2012 seasonal conditions tended to favour early and mid flowering and maturing varieties...
