ARTICLES AND PHOTOGRAPHS BY EMMA LEONARD, UNLESS OTHERWISE STATED BY JOHN HARVEY, EXECUTIVE MANAGER, VARIETIES, GRDC For many growers their first encounter with a new variety will be through the National Variety Trials (NVT). However, the release of a new variety is the culmination of many years work and investment in gene discovery, germplasm enhancement and plant breeding, both in Australia and across the globe. The GRDC's Varieties program aims to provide growers with access to superior varieties to enable effective competition in global grain markets. Strategies to achieve this include: ninvestment in targeted pre-breeding research which is focused on key traits; ninvestments to build and sustain world-leading breeding programs; n development of paths to market for GM traits; and n facilitation of faster adoption of superior varieties. Much of the program's investment is in pre-breeding research to discover and validate novel genes, and to provide germplasm in which such genes have been successfully integrated. These investments will deliver germplasm with improved drought and salinity tolerance and improved disease resistance. By working with the International Maize and Wheat Improvement Center (CIMMYT) and the International Center for Agricultural Research in the Dry Areas (ICARDA), as well as other international collaborations, the GRDC is helping ensure that Australian breeders can access the most appropriate sources of genetic material. Of equal importance are projects that identify appropriate genetic material rapidly, collate and share information, and store genetic material for the long-term benefit of breeding programs. Other investments are in commercial businesses, such as InterGrain and Australian Grain Technologies, which are fundamental to the continuation of breeding of varieties for Australia. People are another important area of investment. By supporting PhD and postdoctoral students, the GRDC is helping to ensure the industry retains the capacity to maintain its high standard of achievement from pre-breeding through to variety delivery. Drought, water-use efficiency, quality issues, disease resistance and frost have been identified by the industry as priority traits that need to be addressed through plant breeding. The GRDC has worked with the industry to establish key national and regional traits. Last year, more than 20 new crop varieties were released. For wheat, the target is to achieve an average annual yield increase of one per cent a year, as measured by the NVT. Of the 14 wheat varieties released in 2008-09, some had yield improvements as great as 11 per cent more than commonly grown varieties suited to the same region. As wheat is the most important grain grown in Australia, it has been selected as the topic of this Ground Cover supplement to demonstrate the breadth of the GRDC's investment in cereal breeding. While this is not a comprehensive report of the GRDC's investments in wheat breeding, the aim is to provide examples within each of the key links in the chain before a variety is released.

The green circles refer to projects in irrigation regions and the blue circles to high-rainfall zone projects, not the other way around as printed.
