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...

The Grains Research and Development Corporation (GRDC) has demonstrated its commitment to cultivating the careers of young grains industry scientists, awarding a travel bursary to Sydney University research fellow Dr Philip Davies... Based at Sydney University's Plant Breeding Institute (PBI) at Narrabri, Dr Davies is now playing a leading role in GRDC-funded crown rot pre-breeding research which assesses the performance of individual breeding lines under crown rot conditions and paves the way for the development of varieties with enhanced crown rot resistance and tolerance... Crown rot is caused by the fungus Fusarium pseudograminearum and is one of the most serious disease threats to winter cereal crops in Australia costing northern growers around $80 million on average each year...

Dr Bob Redden (wearing cap, centre) collecting field pea and faba bean landraces in China.. A field-based method of detecting frost tolerance has been established at Hahndorf in the Adelaide hills.. The new method has been applied to field peas and used to screen Australian and Chinese germplasm..

GRDC honours PBI researcher.. "Dr Davies is a great example of the GRDC's funding of succession plans within industry and he's continuing the work and techniques that were previously developed by his mentor, Dr Richard Trethowan," Mr Clark said... "Researchers such as Dr Davies will play a key role in the industry's future management of crown rot and the GRDC has a responsibility to ensure that these researchers are well supported in their endeavours."..

Crown rot researcher rewarded by GRDC.. Resistance centres on the ability of a plant to halt the invasion or progression of pathogen infection while tolerance is the physiological response of a plant which enables it to mitigate yield loss in spite of pathogen infection... "So we are always going to have to look for those partial sources of resistance and tolerance so the plants can escape yield loss...

Furrow sowing often worsens water repellence.. New research findings confirm grower observations that Western Australia's most common seeding technique - furrow sowing using knife points and press wheels - often exacerbates water repellence on sandplain soils... "But recent evidence shows this technique can in some circumstances actually cause water repellent soil to become concentrated with the seed and fertiliser in the base of the furrow," he said "This may be a result of the flow of dry, water repellent soil around the knife point and into the slot ahead of the closer plate and press wheel...
