Middle: Leaf rust pustules are smaller than stem rust and rarely appear on the back of the leaf... It is unlikely that all growers will apply adequate fungicide at the first sign of rust and keep the infection sufficiently under control so that the disease will not spread to neighbouring properties... Equally it is unrealistic to expect that all growers will sufficiently monitor or destroy volunteers growing between seasons to ensure that those volunteers will not harbour rust infections which may be responsible for starting new epidemics...

Victorian Department of Primary Industries cereal pathologist Dr Grant Hollaway is quantifying yield losses in wheat caused by yellow leaf spot... Scientists are to pinpoint the yield losses attributed to YLS, a disease that is widespread in medium to low-rainfall districts, particularly where stubbles are retained and wheat is grown in tight rotations... Some growers are relying on fungicides for YLS but are unlikely to be achieving complete control of the disease...

After a decade of GRDC supported research, progress is being made in understanding the causes of grain quality defects - pre-harvest sprouting, late-maturity alpha-amylase and black point - that regularly take the gloss off an otherwise profitable crop... Pre-harvest sprouting, late-maturity alpha-amylase and black point are grain quality defects controlled by independent genes, triggered by different weather conditions... Grain from the wheat grown in the screening program is collected and germination tested to establish the level of dormancy...

The proposed project will undertake research to phenotype a high early vigour wheat population (WCD2) developed within GRDC project UA00061... In the extension phase of UA00061, it is proposed to undertake phenotyping for CA of selected lines at 3 different sites with contrasting rainfall over the next 3 growing seasons This data will provide information on the stability of the expression of CA under different environments (G x E)... The proposed project aims to determine the stability of the expression in CA in different environments (G x E) and against different weed species...

The success of the wheat industry in recent decades is due in part to the efforts of plant breeders who have responded to challenges posed by pests, diseases and abiotic stresses by selecting and releasing suitably resistant and adapted cultivars... The wheat rusts pose some of the most serious threats to a prosperous grains industry... The Australian wheat crop has been protected from devastation by rusts for many years by the use in commercial cultivars of effective resistance genes...

A wheat growing project, part of an 'outdoor classroom' program at a Western Australian primary school, has provided an alternative forum for learning that introduces students to grains cropping and the science of plant breeding... After her excellent presentation, she gave us three types of wheat: Federation (released in 1901), Olympic (released in 1956) and Emu Rock (released in 2011)... Our class decided to plant the wheat varieties in our school vegetable garden, then harvest and count the ears from each type of wheat...

Breakthrough may provide climate-tailored wheat.. The scientists used specially designed natural-light-controlled environmental field facilities to grow two pairs of sister lines of wheat contrasting in vigorous growth and tillering to see how predicted future climates are likely to influence the genetic traits that wheat breeders have been selecting for... Professor Siddique has recently discussed the results with breeders from the International Maize and Wheat Improvement Center (CIMMYT) and the International Center for Agricultural Research in the Dry Areas (ICARDA), and would like to screen Australian wheat genotypes using the natural light controlled environmental facilities so breeders have better access to knowledge about the best parental genotypes to select and develop wheat varieties that thrive under hostile climatic conditions...

Diagnostic advances help shut down costly wheat defect.. Many scientists were sceptical when Dr Daryl Mares reported a wheat quality defect that could cause low falling number in the absence of pre-harvest rainfall... Dr Mares and his research group - Dr Kolumbina Mrva, Margaret Pallotta, Dr Klaus Oldach and Dr Judy Cheong - continue their role as lead protagonists in the fight to detect LMA before new wheat varieties reach Australian paddocks and cause the downgrade of otherwise normal-looking grain...

Following a very positive outcome of the review undertaken by GRDC in 2005, GRDC elected to support the activities of the Group for a further two years... The enabled WQOG to provide market-focused quality objectives for Australian wheat breeders, recommendations to GRDC on priorities for quality research, and to act as the designated technical resource to advise the Wheat Classification Council (WCC)... Deregulation of the export wheat market has brought a number of key challenges that must be overcome if the industry is to retain its reputation as a supplier of quality wheat...
