Barley breeders respond to industry in ferment.. "InterGrain is accelerating its efforts to improve resistance to leaf rust, scald and net blotch using formal and informal relationships with state agricultural departments in New South Wales, Victoria, WA and Queensland along with the South Australian Research and Development Institute, the University of Sydney Plant Breeding Institute and the University of Queensland.".. The resistant material - CIho 5791 and Vlamingh - were part of a set of barley differentials comprised of 20 local and 11 international cultivars used to type the fungal isolates.- Ryan Fowler, University of Queensland and Queensland Department of Agriculture, Fisheries and Forestry..

There is a rich diversity of drought avoidance adaptations in annual plants to enable completion of their life cycle without running out of water... One drought avoidance trait in wheat involves plants being able to accumulate a high concentration of water soluble carbohydrates in their stems which can later contribute to yield... Identification of genome regions in these populations will provide the next step towards producing high water soluble carbohydrate accumulating cultivars, which should translate to higher and more stable grain yield under water deficit conditions...

CSIRO has a long track record of making major on-going investment into the genetic improvement of wheat varieties and their agronomy to ensure they fit the target requirements for both the main wheat belt and the High Rainfall Zones of Australia... Underpinning the development of the traits provided to Australian breeders are a series of basic technologies that we are applying to our work... We outline the state of current research efforts supported by public funds (CSIRO, GRDC) with particular emphasis being given to developments that we believe will assist plant breeders in Australian breeding companies to deliver new high quality, well adapted productive wheats that have the ability to counter major constraint factors...

Two genes related to dormancy (which prevents untimely germination leading to pre-harvest sprouting) have been discovered.. New gene-discovery techniques also mean an accelerated process for isolating potentially important wheat genes for other traits.. In terms of knowing which grain-growing regions these genes will work in, given that not all varieties are suited across the country, Dr Gubler says it is not known how these genes actually confer dormancy, although the researchers do know the expression of the genes is suppressed by high temperatures during grain development - and this then elevates the risk of PHS...

Durum production in the southern region fell in the lead-up to this project... Samples from affected trials have been sent to a DNA laboratory for a quantitative assessment of fungal DNA. Irrespective of the mechanism, this germplasm appears to represent an improvement in field performance under disease pressure... Further research is required to complete this study and develop a more precise understanding of how the environment affects yellow pigment content...

Historic germplasm exchange to lift Australian oilseeds By Dr Gio Braidotti An historic research collaboration between India, China and Australia, in which oilseed germplasm has been exchanged, is giving Australian breeders unprecedented access to a range of advanced key traits for Australia's oilseed industries... The collaboration has overcome previously restricted access to genetic resources in India and China, allowing Australian breeders to now access germplasm with the potential to deliver traits such as increased tolerance to drought and to major diseases... But in other instances researchers are first checking that the lines give the same level of trait expression in Australian environments as they did in India or China prior to transfer...

Stay-green wheat may weaken drought's grip.. Stay-green was discovered in wheat more than 25 years ago, but the traits are only now becoming accessible to breeders through the development of molecular markers, the details of which will be published this year... Stay-green in plants can be determined by a range of underlying mechanisms, several of which facilitate increased water availability after flowering, such as small canopy size at flowering, increased moisture uptake after flowering, increased nitrogen uptake during grain-fill and increased nitrogen in leaves...
