Catalogue: GRDC Research Summaries
The project will undertake an ambitious field program across South Australia and Victoria to evaluate the different resistance genes available to wheat breeding programs to determine the level of resistance required to manage CCN, Pratylenchus neglectus and P. thornei populations in current farming systems, and develop recommendations to breeding companies on the need for resistant and tolerant varieties across the southern region... To improve recommendation to growers, the project will also assess tolerance of current wheat and barley varieties to CCN, P. neglectus and P. thornei and update guidelines on use of nematode resistant and tolerant varieties to minimise yield losses, including revising the risk categories based on initial nematode levels... A new research officer Sjaan Davey, has been appointed to this project and in collaboration with Dr Grant Hollaway,DPI Vic (via GRDC project DAV00104), and Bev Gogel and Prof Brian Cullis (GRDC project, Statistics for the Australian Grains Industry), is co-ordinating field trials in SA and Victoria to check the calibration of the pot experiments used to classify the resistance levels to CCN, Pratylenchus neglectus and P. thornei in new varieties, and is developing a field program to assess how well new varieties tolerate the nematodes in the current farming systems...

New stream, assay system to be developed, screening and characterisation of isolates and field trials, with decision points in Dec 2014 after initial glasshouse assays and March 2017 to engage commercial partner... The major foci of this project are to screen and identify elite disease-suppressive microbes for cereals and nodulation-enhancing beneficial microbes for legumes... The Program will consult and work with potential commercial partners, eg Novozymes Biologicals, Becker Underwood, New-Edge Microbials, ALOSCA Technologies, thereby providing mechanisms to ensure communication of research outcomes and successful commercialisation of inoculant products...

You typically find that the depth to the salt bulge decreases to the west... We have concluded that chickpeas were not as effective as wheat in adjusting yield components under prolonged water stress... The grain yield in the SF early burn and cultivated treatment (2.5 t/ha) was comparable to the other SF treatments in the dry 2002 season despite having the lowest incidence of crown rot infection...

By screening and field testing the resistance and tolerance of wheat and barley cultivars, relevant information can be supplied to allow growers to incorporate cultivars into rotations that limit the populations of and damage caused by nematodes... Significant yield impacts occurred for wheat varieties assessed in Toodyay 2012 when comparing yield to nematode numbers at anthesis (Table 2)... Coupled with resistance data, these results indicate Emu Rock may be only moderately susceptible but very intolerant to P. teres while the other varieties are intolerant but range in levels of susceptibility to the pest...

The review demonstrated the safety and natural occurrence of ethyl formate in the diet... In bin fumigant monitoring: In each trial, ethyl formate and CO 2 levels were measured in five critical places in the silos except Trial 6 in which measurements were taken from one position only... Monitoring systems: The Miran SapphIRe (Thermo Environmental Instruments) programmable infra-red gas analyser was used to measure ethyl formate without interference by CO 2 at occupational exposure levels (100 ppm) and below...

Western Australian research is fine-tuning sprouting tolerance ratings for wheat, to help growers identify varieties less likely to sprout during wet conditions at the end of the cropping season... Research into pre-harvest sprouting has been conducted over recent years by the Department of Agriculture and Food (DAFWA), with funding from the Grains Research and Development Corporation (GRDC), as part of the project 'Wheat agronomy - building system profitability in the western region'... Caption: GRDC western regional panellist Gemma Walker, who farms in the Esperance region where sprouting has been an issue this year, says pre-harvest sprouting research by DAFWA in WA has included field trials and the use of rain simulators...
