" Pulse germplasm enhancement - vegetative and reproductive frost tolerance in pulse crops DAS00066 Start Date: 01/01/2006.. The final year of this project was used to confirm earlier findings and develop the concept of field-based screening for phase II of the germplasm enhancement (GE) program linked to Pulse Breeding Australia (PBA)... The expected outcome of this project was the development of frost tolerant germplasm in field peas, chickpeas and lentils which could be used to develop new varieties that would ultimately sustain and expand the pulse crop production area and provide increased yield and improved grain quality...

Frost nurseries identify tolerant grain varieties.. Pre-breeding research funded by the Grains Research and Development Corporation (GRDC) has identified improved genetic sources of frost tolerance, and these genes are already part of barley breeding programs and under evaluation for wheat... "Future work will continue refining screening methods, searching for sources of tolerance, work towards developing frost sensitivity ratings of new varieties and validate the impact of frost induced sterility from mild frosts on yield in wheat and barley," Dr Biddulph said...

Flow on effects from this optimism include members making effective investment decisions regarding paddock variation management strategies, soil health practices and innovative enterprises - all of which lead to future farm sustainability... The growers had a well established evaluation process enabling them to lower the risk when leasing extra cropping land... The technical audit survey results show 75% of growers in the Liebe Group region use a farm consultant on an on-going basis...

The research highlighted that Northern Region (NR) wheat and barley varieties differed considerably in their sensitivity to these herbicides... The information generated from this project has the potential to save approximately 20 per cent crop income, as indicated by the 3 to 38 per cent significant yield losses measured for certain cultivars from registered herbicides at the recommended rates... The results from this and the previous projects have identified those cultivar x herbicide combinations that may cause significant yield losses at the herbicide recommended rate and timing...

Among cereal variety x herbicide combinations evaluated, 10% of wheat, 9% of barley and 26% of oat treatments were found to result in significant yield losses (3-54%) in one or more seasons... Overall, 115 barley variety x herbicide combinations, 158 wheat variety x herbicide combinations and 88 oat variety x herbicide combinations were evaluated at label rates... Overall, 18 lentil variety x herbicide combinations, 24 faba bean variety x herbicide combinations, 45 field pea x herbicide combinations and 30 chickpea x herbicide combinations were evaluated at label recommended and 2 x recommended application rates and timings...

The cost of soil acidity to agriculture is recognised as being great, especially in Western Australia where the most recent analysis estimates 30% of dryland agricultural soils have subsurface acidity - or are at high risk of developing subsurface acidity - which causes a decline in wheat yield of between 20 and 40% (GRDC Project UWA00081)... The most recent analysis estimates that 30% or 5-6 million hectares of dryland agricultural soils have subsurface acidity or are at high risk of developing subsurface acidity which causes a decline in wheat yield of between 20 and 40% (GRDC Project UWA00081)... The experience and machinery developed as a result of this work is currently being passed on and used by the SIP08 project UWA00081 and will be used where applicable by Wal Anderson's new GRDC project 'Enhancing paddock profitability - a collaborative diagnostic approach to cropping systems research'...

The RCSNs - comprising growers and industry professionals in each port zone - have also invested limited discretionary GRDC funds into 'fast-tracked', short-term projects to address pressing crop production constraints facing local growers... Growers may be interested to know that the GRDC has increased its investment in WA RCSN projects to $750,000 this year... The GRDC looks forward to extending the results from these and other 2014 RCSN projects when they become available...
