A common (genetic) denominator has been discovered for wheat's acute sensitivity to stress - from drought, heat or frost - at flowering... The finding stems from the discovery of a common biological response to different kinds of environmental stresses... Dr Dolferus arrived at this concept by integrating many, disparate field observations in which plants subjected to different stresses all ultimately responded the same way - by aborting the development of pollen...

Single trait may give wheat a bulletproof vest.. "The lines that contain the QTLs for drought and shading tolerance will now be tested in future trials for tolerance to other stresses such as heat stress, to confirm that the tolerance trait is shared by different stresses," Dr Dolferus says... The material is ideal for getting a better understanding about what is happening 'under the bonnet'."..

Corn developmental stages used in this article are based upon the Iowa State Publication "How a Corn Plant Develops" (Ritchie et al., 1997)... The paper provides an illustration of the application of these tools to example farms and farming systems on the Atherton Tableland... of application improves penetration into the canopy - 8 km/hr is the maximum..

Drought tolerance, disease resistance and yield top the priorities list for researchers assessing maize germplasm to improve varieties better suited to Australian tropical and subtropical farming systems... Dr Fekybelu says growers who produce maize as a summer crop often see it as unreliable and high risk, particularly in drier environments... Dr Fekybelu says the objective has been achieved in the first two years, with some lines showing a 20 per_cent increase in yield...

The SAGIT funded project involves using a controlled environment assay that is run at Roseworthy, to identify and quantify the level of heat stress tolerance in current varieties, advanced breeders lines and exotic lines, as well as using 'gene mapping', to genetically dissect and understand the key sources of tolerance identified to date... Figure 1 illustrates the fertility and grain size response for a subset of varieties to heat stress in the controlled environment assay. In general heat stress causes a significant (p<0.05) reduction in both grain number and grain size, the two key yield components and ultimately grain yield... A subset of exotic introductions that have been screened for heat stress tolerance in the controlled environment assay, showing diverse levels of adaption...

Australian Grain Technologies, with funding from the South Australian Grains Industry Trust, is using heat chambers as part of its research examining wheat traits important to heat-stress tolerance... Research funded by the South Australian Grains Industry Trust (SAGIT) and the GRDC at Australian Grain Technologies (AGT) is investigating wheat traits that are important to heat stress tolerance, undertaking genetic mapping of genomic regions affecting heat tolerance and characterising parents to select for this trait... Breeders could potentially select for heat tolerance using traits for grain number, size and rate of filling under heat stress...

Farm advisory boards can strengthen accountability.. Unlike the mainstream small business sector, only a minority of Australian farms have an advisory board where the intellectual contributions of family members and outsiders are brought together at the same time... A Grains Research and Development Corporation (GRDC) Farm Advisory Board Fact Sheet outlines how advisory boards can contribute to an improved bottom line by providing decision support, setting guidelines for prudent budgeting and expenditure, and keeping people informed and ready for new opportunities and innovations...
