The project has focused on monitoring blackleg populations for virulence by exploiting markers for avirulence (Avr) genes in the fungus, which are complementary to resistance (Rlm) genes in the plant... Selection pressure acting on one avirulence gene can also influence other avirulence genes that are closely linked... Only two genes (LmCys2 and AvrLm6) have mutations in attacking isolates and are considered candidate genes...

Balansa has good levels of hard seed which allow balansa clover to regenerate well after a season of cropping... Mid and late maturing varieties of balansa clover are commercially available, and this range allows the species to be grown in areas receiving between 350 and 800 mm of annual rainfall... Balansa clover grows best in monoculture; good performance with perennial grasses or short-lived ryegrass has been reported...

Choose a cultivar with adequate blackleg resistance for your region... For individual site results consult the NVTonline website... Background: Blackleg disease can be minimised by a number of factors including sowing cultivars with high blackleg resistance, avoiding sowing in close proximity to last year's stubble and applying fungicides (see the current Blackleg Management Guide for details www.grdc.com.au)...

Choose a cultivar with adequate blackleg resistance for your region... For individual site results consult the NVTonline website... Background: Blackleg disease can be minimised by a number of factors including sowing cultivars with high blackleg resistance, avoid sowing canola in close proximity to last year's stubble and applying fungicides (see the current Blackleg Management Guide for details - www.grdc.com.au)...

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...

We have applied late nitrogen over the past two seasons to a portion of our wheat crop to successfully grow and deliver Prime Hard (PH) wheat... My plan is for this paddock to receive top-dress nitrogen in late September or early October for PH 13% to 14% protein, only, if the profile is full and budgets indicate it is worth the risk... Goulburn has hard seed levels of 30% measured at the end of April...

Identify the most appropriate methodology of single isolate screening of resistance genes in Australian oilseed Brassica lines... To successfully breed new blackleg resistant cultivars breeders need to know which resistance genes are already deployed, which are no longer effective (pathogen has overcome resistance) and which resistance genes are to be exploited... If resistance genes are overcome by the pathogen we need to be able to tell growers which cultivars are likely to be affected and which cultivars to avoid...
