Catalogue: GRDC 2014 Research Summaries
Production of wheat is limited by many abiotic and biotic stresses... The project will consolidate initial achievements and aims to: i) Identify and develop high yielding, widely adapted germplasm with tolerance/resistance to terminal heat and drought stress ii) Transfer reputed heat and drought tolerance genes into Australian elite wheat backgrounds... iii) Identify potentially new sources of resistance to fungal diseases such as yellow rust and septoria, and incorporate those into adapted Australian genetic backgrounds to broaden the genetic base of resistance to diseases iv) Identify molecular markers closely linked to heat and drought tolerance genes and validate them in Australian wheat backgrounds...

After the plants have grown for 18 weeks, the nematodes are extracted from the soil and roots, and counted under a microscope to determine which plant lines have reduced nematode multiplication... Root-lesion nematodes (RLN) are considered most likely endemic to the Fertile Crescent region in the Middle East where wheat originated some 8,000 years BCE. From there, RLN probably spread around the world with grain cultivation across North Africa, Europe, America, and finally Australia... "We realised the resistances that aren't available in commercial wheats, do exist in their ancient ancestors," says Professor John Thompson, Crop Nematologist at University of Southern Queensland' who supervises the GRDC-funded wheat pre-breeding program into genetic options for RLN control...

John piper and his family use a 60-tonne Kotzur drying silo to enable them to harvest over-moisture grain and dry it to end-user specifications... When showers of rain started in March - which went on to total 134 millimetres for the month - the Pipers' elected to harvest what was left of their sorghum at 15 per_cent moisture and hold it under aeration cooling until the grain could be blended or dried... For the 2010-11 winter harvest, John says having the capacity to hold a portion of their wheat under aeration cooling for sale at a later date was beneficial as some wheat and barley crops within the district were penalised heavily due to the suspected presence of fusarium head blight and white grain disorder.
