Catalogue: 
The project focused on colour stability (darkening) of Asian noodles and has provided strategies for improvement of Australian wheat varieties and better management of quality of grain shipments going to high value markets... Significant research is still required to understand the genetic and environmental control of constituents that determine the creamy to yellow colour of noodles and pasta variation that can occur along the production to use chain... Darkening in noodles measured as a loss in brightness (CIE L*) was separated into two main time periods, 0-4hours and 4-24hours...

The objectives of the work were the development of vigorous, long coleoptile wheat germplasm; the release of cycle 4 recurrent selection (RS) high vigour germplasm; and enhanced selection efficiency through genetic studies of early vigour and coleoptile length.. Mean squares for general combining ability (GCA), specific combining ability (SCA) and reciprocal effects for coleoptile length and diameter measured on parental and F 1progeny from a 12 12 wheat diallel grown at four different soil temperatures (11, 15, 19 and 23 C)... In summary, work in Output 3 resulted in: 1...

Durum production in the southern region fell in the lead-up to this project... Samples from affected trials have been sent to a DNA laboratory for a quantitative assessment of fungal DNA. Irrespective of the mechanism, this germplasm appears to represent an improvement in field performance under disease pressure... Further research is required to complete this study and develop a more precise understanding of how the environment affects yellow pigment content...
Catalogue: 
The variability of ammonia volatilisation (5-26% of applied urea nitrogen (N)) associated with initial moisture status and the occurrence of follow-up rain leads to the conclusion that sophisticated modelling of this process is unlikely to be practical for accounting purposes... Large nitric oxide emissions are linked to rising nitrate concentrations in soil... While small emissions of nitric oxide occur during periods of near-constant soil nitrate concentration, large nitric oxide emissions are linked to rising nitrate concentrations in soil...

Catalogue: 
Barley with genetically unique sources of adaptation to the low rainfall environments has been evaluated using lines from the International Centre for Agricultural Research in the Dry Areas (ICARDA)... Barley lines from ICARDA have shown potential for the improvement of adaptation, with adaptive features derived from wild barley and primitive barley landraces, and selection for yield and associated adaptive traits in drought prone environments with soils of low fertility... The germplasm and information gathered in this project will benefit industry since the project has had a focus on the...

" Pulse Industry Extension - Expanding pulse cropping by targeted extension of improved varieties and management packages DAW00100 Start Date: 01/07/2004.. Overcoming the barrier of harvesting field peas by promoting the role and value of semi-leafless varieties, in combination with appropriate management, should result in growers and their advisers treating field peas as a legitimate crop choice in any given year... The project will allow continuity of staff and experience about field peas throughout WA during its expansion phase, and provide growers with the necessary technical back-up ...

The aim of the study was to evaluate the impact of subsurface (below plough layer) and subsoil (B horizon) constraints on the performance of canola... The inclusion of canola in the cropping rotation underpinned unprecedented wheat yield improvements in many areas during the 1990s... Canola was generally considered more sensitive than wheat to hardpans, water logging and soil acidity but less sensitive to salinity and boron toxicity, although no comprehensive studies have been carried out to confirm these observations...

The program of research for this Chair in Crop Science focused on novel integrated systems modelling approaches for grain crop improvement... Experiments have been conducted in the new lysimetry platform to explore the physiology and genetics of key drought adaptive traits, such as transpiration efficiency and carbohydrate partitioning among organs... Chenu, K., Chapman, S.C., Tardieu, F., McLean, G., Welcker, C., and Hammer, G.L. (2009) Simulating the yield impacts of organ-level quantitative trait loci associated with drought response in maize - A "gene-to-phenotype" modeling approach...

The current project provided an extra period of time to continue this process and extend the outcome to a wider audience through participation in workshops, field days and farmer updates... As the project has achieved its aim of deriving and subsequently offering some solutions to a wide audience of farmers, advisers and researchers over a considerable period of time, there is no need for it to continue... As the project was an extension of the previously reported project ACR4, the expected outcome is as previously reported for that project with an extension of the message to a further aud...

Catalogue: 
The occurrence of high levels of salts, sodium and chlorides (Cl) in the northern grains region subsoils effectively reduces rooting depths, increases osmotic potential and chloride toxicity, and reduces the crop water use from the soil profile... The Decision Tree and toolkit developed in this project have become essential components of identifying and managing subsoil constraints (SSC) for advisers and growers... More recent research was carried out in project DNR00008 Advanced Techniques for Managing Subsoil Constraints...
