Field work was carried out using rain-out shelters and irrigation facilities at the Department of Agriculture and Food WA's (DAFWA) Merredin Research Station (MRS) (2008 and 2009)... The distribution of rainfall had the greatest (but inconsistent) effect on yield, followed by management (row spacing)... In the long term, genetic improvements using specific traits to increase yield under dry conditions may deliver greater benefits to growers...

Studies within the project have shown that some of the newly identified slow rusting genes have pleiotropic effects on multiple diseases... In the first phase of this project, this partnership led to the cloning of the first adult plant resistance gene, Lr34/Yr18/Pm38 and the development of a gene-based molecular marker that is routinely being used by many breeding programs worldwide... In 2012, Australian wheat, durum and triticale varieties were also evaluated for stripe rust, as well as for leaf rust in Mexico with prevalent races that constitute an important threat to wheat production if introduced to Australia...

Screening of rust resistance in key stages of the breeding program (parent evaluation, segregating and fixed breeding lines) has integrated rust resistant lines into all stages of the breeding process... Important factors in production risk addressed in this project were susceptibility to rust diseases (stem, stripe and leaf rusts) and intolerance of pre-harvest sprouting... Sustained routine evaluation of rust resistance in key stages of the breeding program including parent evaluation, early (segregating) and late (fixed) breeding lines, including both field and glasshouse screening approaches...

One of the most effective weapons in the battle against annual ryegrass is growing a competitive crop... The outcome of Project ACR2/4 was assessed from this viewpoint over its eight-year life... Clover pasture - ST 0 0 36.3* 68 2000 - - 24/6 - Westonia wheat (100) 0 0 2.61 316 2001 SB C 6/6 - Arrino wheat (100) 0 0 3.62 726 2002 SB C 10/6 - Westonia wheat (100) 8 8 1.42 186 2003 NB - 2/6 - Arrino wheat (100) 8 8 3.58 541 2004 SB - 1/6 - Westonia wheat (130) 10 5 3.36 315 8 year cumulative 68 2137 w= kg ha -1wool the excellent result within this block is clearly linked to two major factors: o a generous period of time out of crop presenting an opportunity for a significant weed break...

Mention of a trade name or company in this publication does not imply endorsement of any product or company by the Department of Agriculture and Food, Western Australia... Overall, the production and supply of fertiliser accounted for a large proportion (35%) of the GHG produced from wheat production, and occurred in the pre-farm stage (Table 1)... Overall, constraints have a far smaller effect on heavy soils than on sand plain soils...

To give us a better understanding of how much water was remaining in the soil if we wanted to undertake forward marketing decisions for our crops... We wanted a tool to give us a better understanding of how much moisture we had remaining in the soil profile (and where it was located) before making a decision to spread N. The soil moisture probes give us this ability... Following our experience with forward marketing we wanted a better decision tool to help us decide if we had enough moisture to grow a crop and make forward sales and probably more importantly following 2007, know when the crop is about to run out of moisture and if options such as purchasing grain contracts back needs to be carried out...

Plant breeders have made great progress in improving disease resistance but much less progress improving the adaptation of wheat to drought and high temperature... There is a need to establish better methods for assessing drought and heat tolerance under field conditions to support Australian wheat breeding... The establishment of a managed environment facility (MEF) in the field at Narrabri provides a means of making accurate, repeatable and relevant measurements of drought and heat response in wheat...

The project will generate tools that allow the delivery of durable resistance to rust diseases in the Australian wheat crop through: 1... In the shorter term accurate DNA markers referred to as 'Breeders' Markers' and newly characterised resistance genes will be made available for immediate use by Australian wheat breeders as soon as they are verified and then internationally via peer reviewed publication in scientific journals... The expected outputs of this project are a set of accurate DNA makers for known and new rust resistance genes of high relevance to controlling the three wheat rust species (stem rust, stripe rust and leaf rust) in Australia and overseas...

The GRDC has teamed with Bayer CropScience and CSIRO to create a new research partnership dedicated to breaking through the yield ceiling that has been holding back wheat production globally... The GRDC and CSIRO funded the initial research and now Bayer CropScience has joined the partnership to support the next stage of development... Mathias Kremer, head of the BioScience business unit at Bayer CropScience, says the company has already been working on the development of wheat varieties with higher yield, more efficient nutrient utilisation and tolerance against drought and heat stresses, and that the CSIRO's gene development offers an exciting new approach...
