leaf rust resistance

Catalogue: GRDC Final Reports
One Avena abyssinica and one Avena strigosa accession had resistance to the most virulent strains of leaf rust but none were resistant to the most virulent stem rust strains... The principal expected outcomes of this project are improved yield potential and grain quality unattainable by conventional breeding methods plus lower production costs for oat growers, processors and exporters... The techniques used in this work are a valuable method for obtaining new genetic resistance to important leaf diseases without the need for genetic modification technology that has not been accepted by the community or market...

Vigilance call for barley leaf rust.. Mr Platz urges growers to be alert to the risks of a leaf rust outbreak: "The risks may be low this season, but that's no reason to become complacent," he says. ".. "Managing the disease requires a community effort, so if a grower locates leaf rust they should alert their regional departmental pathologist so a general alert can be issued," Mr Platz says...

Watch and be prepared to act on cereal rust.. DAFWA researchers across the WA wheatbelt are closely monitoring volunteer cereals and emerging cereal crops for the presence of leaf rust - as well as other diseases, viruses and pests... Geoff Thomas advises growers and advisers to monitor volunteers, particularly of S varieties such as Stiletto, and to be prepared if fungicide management of leaf rust is required this season...

The disease was present throughout the region and fungicide was applied to some crops in Queensland to control the disease... The crop was being monitored for spot form net blotch when mottling on the leaves alerted the agronomist to the presence of leaf rust... Finally foliar applied propiconazole was effective in controlling leaf rust in these crops...

Watch and be prepared to act on cereal rust.. It is recommended WA growers and advisers closely monitor advanced cereal volunteers and emerging cereal crops for the presence of leaf rusts ( Puccinia triticina and Puccinia hordei ) this season - along with other rust diseases, viruses and pests... Geoff Thomas advises growers and advisers to monitor volunteers, particularly of S varieties such as Stiletto, and to be prepared if fungicide management of leaf rust is required this season...

A new source of leaf rust resistance from a wild diploid Avena species was successfully transferred to a Wintaroo derived breeding line... Several new sources of stem rust resistance were identified in wild oat species with partial resistance to Pga 512, the most virulent strain in Australia for which there are no other known sources of resistance... Further investigations need to be conducted to determine if these two molecular markers are reliable indicators of the presence of the alien chromosome carrying leaf rust resistance...

The future of oat stem rust resistance in Australia depends on identifying and introgressing new sources of resistance into adapted varieties in conjunction with strategies recommended for the new Australian Cereal Rust Control Program... The project will use cytogenetic techniques to transfer sources of stem and leaf rust resistance from wild oat species into breeding lines which can be easily used by breeders to develop new rust resistant oat varieties... The project builds on the results of two previous GRDC funded projects, DAS00031 and DAS00074 which demonstrated the existence of novel sources of leaf rust resistance in the wild oat species Avena strigosa and A abyssinica, and stem rust resistance in A damascena, A longiglumis, A murphyi, A prostrata and A sterilis...

Discovery of new leaf rust pathotypes in Western Australia during 2013 has prompted a warning about careful cereal rust management in 2014... Detection of new leaf rust pathotypes in 2013 that can overcome resistance in wheat and barley cultivars has highlighted the importance of implementing up-to-date cereal rust management plans this year... Growers are advised to check updated disease resistance ratings in the 2014 GRDC and Department of Agriculture and Food, Western Australia (DAFWA), wheat and barley variety guides, and choose varieties carefully to minimise the risk of crop damage...

The project has succeeded in its objective of producing new stem and leaf rust resistant lines containing chromosome segments from alien species and making them available for protection of wheat crops in Australia... Recombinant lines carrying shortened alien chromosomes with Sr32, Sr2S#1 and Sr39 produced in earlier GRDC projects have been confirmed and made available to wheat breeders around Australia since 2004... , advanced backcrossed lines carrying stem rust resistance derived from three different Triticum speltoides accessions or amphiploids and two sources of leaf rust resistance from T. searsii and T. tripsacoides have been produced...
