Dr Phil Davies from SARDI checks the performance of field pea plants in a trial at the University of Adelaide's Waite campus in South Australia... "The heat-stress tolerance is due to several genes dispersed across the genome - a situation that makes it difficult to breed all genes into elite cultivars without the genes becoming separated during the genetic recombination that occurs during sexual reproduction," Dr Davies says... Dr Davies has found there is sufficient interest in the trait to pursue molecular markers, which may provide a viable way to rapidly select for these heat-tolerance genes using a cost-effective DNA typing technology favoured by breeders...

Research funded by the Grains Research and Development Corporation (GRDC) has produced new germplasm, screening methods and selection tools to speed up the production of varieties less susceptible to pre-harvest sprouting, late-maturity alpha-amylase (LMA) and black point (BP)... LMA is genetic defect which, like sprouting, may be triggered by environmental conditions and results in the production of alpha-amylase - an enzyme which can degrade grain starch - measured by 'falling number' tests at delivery... " in collaboration with local and international researchers, the projects based at the University of Adelaide have identified genetic material which influences these defects, and developed new molecular marker tools," Associate Professor Mares said...

International Maize and Wheat Improvement Center (CIMMYT) and the International Center for Agricultural Research in the Dry Areas (ICARDA) germplasm has the potential to contribute significantly to the development of new wheat cultivars for Australian cultivation... The proposed project will cooperate directly with the proposed "Information Coordination/Communication", "Germplasm Evaluation" projects and the "CIMMYT Germplasm Selection and Export" project to ensure that only that germplasm specifically identified for evaluation and utilization in Australia is efficiently sourced from CIMMYT, fully documented, grown in approved post-entry quarantine facilities according to AQIS Import Permit requirements, and upon release from quarantine seed will be provided to the.. The bread wheat industry in Australia will benefit directly from the success of this project through the earlier and more efficient identification and introduction of the CIMMYT/ICARDA germplasm of most interest to Australian breeding programs...

Combinations of genes determine the classification of wheat into classes from Prime Hard to Feed,influence time of flowering from different sowing dates at different locations, determine disease resistance, and ultimately influence grain yield... Understanding the combinations of genes that produce elite varieties enables Australian wheat breeders to substantially accelerate the rate of genetic progress in breeding programs... Utilisation by breeders of the information generated is rapid...

Demand for high quality malting barley is growing and in particular we need to target 1... South Australian grower, Mark Branson is involved in growing a new barley variety called Charger which is used in a closed loop arrangement by the Carlsberg and Heineken companies... If you downed a glass of Carlsberg or Heineken beer recently, there is a fair chance you drank barley grown by Mark Branson...

WA typically produces 40 per cent of the national wheat crop and of this approximately 95 per cent is sold overseas, mostly to the Asian and Middle Eastern markets, so it's important to determine and meet market needs... Average annual growth in wheat productivity in Australia has been about one per cent for the 20th century, until the 1980s, with the agronomic breakthrough associated with minimum tillage, when it became closer to four per cent, of which a quarter is attributed to better cultivars developed by wheat breeders... Senior InterGrain Wheat Breeder, Robin Wilson, says that the blend of traditional breeding with molecular marker techniques provides advantage in that breeders can better target genetic combinations they need to deliver simultaneously on yield, disease resistance, stress tolerance and quality...

The ultimate goal of the Lentil Genome Sequencing Consortium is to provide the most comprehensive foundation possible for the future development of DNA-based breeding tools and technologies - including marker-assisted selection - for use by pulse breeders, including Pulse Breeding Australia (PBA)... What the consortium wants to do for the lentil is provide a route to systematically understand the genetic basis of diversity in lentil populations and its impacts on plant characteristics in the paddock... At the stage, the genome project can provide essential tools for use in pulse germplasm enhancement, including molecular markers aimed at specific traits of interest such as disease resistance, abiotic stress tolerance and herbicide tolerance...

The problem is even bigger at the global scale, with total cost of salinity estimated over $11 billion per year... Salinity issue will remain one of the key threats to the global food production in the 21st century... The project will contribute to this goal by providing physiological evaluation and mapping appropriate genes conferring two of such traits, namely transpirational control and oxidative stress tolerance, in cereals...
