Livingston is one of few varieties that has moderate tolerance to root lesion nematodes (RLN), along with other desirable features... The researchers concluded that where Pt combines with high levels of crown rot (a common scenario), yield losses can be exacerbated if varieties are susceptible to Pt. Instead of a 10 per cent yield loss from Pt in a susceptible variety it could be 30 to 50 per cent if crown rot is combined with a Pt-intolerant variety...

About 200 breeding lines were exchanged between the three countries to improve resistance to the diseases blackleg, white rust and sclerotinia and also tolerance to pod shattering, drought and high temperatures, plus the traits required for canola-quality mustard... During two exchanges, 106 breeding lines of Brassica napus and 104 of B. juncea were exchanged between the three countries... All countries will benefit, with India and China seeking to replace their traditional rapeseed and mustard cultivars with Australian canola-quality (low erucic acid, low glucosinolate) B. napus varieties," Associate Professor Salisbury says...

Rust's genetic resistance explored via award.. Professor Park says that pathogens reduce yields of the eight most important crops by a staggering 42 per cent and the most effective, economical and environmentally sound way to control rust diseases is to develop and cultivate varieties with genetic resistance. ".. The rust species can destroy entire crops, with Australia's last outbreak, in 1973, costing the wheat industry an estimated $300 million...

Kevin Kilby is hoping research will eventually come up with a cheaper, more effective way to control fallow weeds like fleabane... The coming season has the potential - courtesy of well-soaked soils - to deliver above-average yields, but Kevin is quick to point out that recent history has shown nothing can be taken for granted... Kevin soil-tests about 40 per cent of his paddocks to gain a broad picture of his nutrient needs, but hasn't invested in variable-rate technologies, saying weed control has the biggest influence on his crops' performance and that, for the moment, remains the priority...

Alan Bowring who is researching the role of head and flag leaf development in contributing to wheat yield... New research is suggesting lower leaves contribute more to wheat yield than is currently the "accepted norm" - under which protection of the flag leaf is the principal determinant of grain yield... In similar cool long season conditions in Australia this also seems to be the case in more difficult hot, dry seasons in northern Australia, Alan Bowring's results suggest that the importance of the flag leaf is about half of what is accepted in the UK. His data indicates that in these dry conditions the earlier leaves preceding the flag leaf (especially the preceding two; flag leaf -1 and -2) have a similar overall contribution to yield as the flag leaf, at least in environments such as northern NSW. Contribution to yield of pre-flowering stem reserves was assessed in the research and is believed to contribute between 16 and 21 per_cent by remobilisation of sugars and proteins to the grain...

Crop management practices key for SA grain growers in 2012 Suppression of crop diseases, pests and weeds will be critical for South Australian grain growers looking to maximise productivity from their plantings in 2012... Mr Shannon said the two-day Update was designed to equip advisers and consultants with the latest agronomic information and resources - delivered by industry experts from throughout Australia and around the globe - to guide and support grain growers over the coming year... Expectations of another big canola crop going in this year has generated widespread concern among industry authorities about the potential for a high risk of blackleg disease," Mr Shannon said. "..

Webcast heralds new age for industry debate.. The panel, chaired by the national editor of ABC Rural, Leigh Radford, and including GRDC managing director John Harvey, discussed how breeding could overcome the 'tough nuts' facing Australia's wheat growers - frost, drought and protection from disease... The rodent panel included three members of the National Mouse Management Working Group - Dr Rohan Rainbow (GRDC manager crop protection), Dr Simon Humphrys (commercialisation manager, Invasive Animals Cooperative Research Centre) and Andrew Polkinghorne (South Australian Mouse Working Party) - and addressed an increase in mouse numbers in an area covering more than a fifth of south-east Australia's cropping area...
