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...

Breakthrough finds wheat's vital sleeper gene.. Two bread wheat genes that provide resistance to pre-harvest sprouting - one of the main impediments to consistent grain quality - have been identified by CSIRO's Agriculture Flagship in a GRDC project... The resistance was thought to be due to the existence of genes collectively called 'dormancy genes' because of their ability to suppress germination (keep seed asleep, so to speak) under conditions that would otherwise lead to pre-harvest sprouting...

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...

The genetics of brewing better beer.. Genetic analysis shows that malting barley grown under Australian conditions requires a finer balance between malting quality and pre-harvest sprouting tolerance than its Canadian counterparts.. The market has a strong preference for the malting flavour of Canadian barley and is often willing to pay a $50-per-tonne premium for it...
