pathotype

Catalogue: Ground Cover
Exotic rust find in SA.. Every year since 1919 staff at the University of Sydney have monitored Australian cereal rust populations using samples of rusted plant material collected throughout Australia... In September 2014 the new pathotype was found in leaf rust samples collected from Mount Hope on the Eyre Peninsula ( Wyalkatchem ) and Moonta ( Axe ) and Port Broughton ( Corack ) on the Yorke Peninsula...

The stripe rust pathogen of wheat prefers lower temperatures and has only been found twice during the summer months in Australia since 1979 when it first appeared ... Samples of stem rust from volunteer wheat forwarded to the ACRCP annual rust survey from WA and SA during the summer/autumn period earlier this year were almost exclusively identified as pathotype 34-1,2,7 +Sr38... In view of the presence of stem rust inoculum in the summer and autumn period and the pathotype present in WA and SA, the cultivars Calingiri, Yitpi , Camm and Pugsley may need monitoring for stem rust come spring...

The discovery of a new pathotype overcoming the resistance gene Yr17 has been widely reported since the first announcement, just before Christmas 2006... What we don't know: the expected response of Yr17 varieties - this can only be determined in field experiments in the 2007 season and data will be made available as it comes on line, hopefully in early to mid-spring; where, or if, the new pathotype will survive summer, and in what quantities; and whether the new pathotype will establish in the first season - or whether it will take several seasons to become frequent in the pathogen population...

The paper will review the nature and origins of these new pathotypes, and indicate the expected changes in variety response for the 2008 season... These three isolates look different on these wheats, and so we give each the name of 'pathotype', ie it is a 'type' of the pathogen... The first major pathotype change in the WA pathotype occurred in October 2006 when isolates collected from Coleambally (NSW) and Horsham (Victoria) showed the ability to cause disease on plants with the Yr17 resistance gene...

These three isolates look different on these wheats, and so we give each the name of 'pathotype', ie it is a 'type' of the pathogen... The second pathotype change was detected among isolates collected early in the 2007 season, and these showed the ability to cause disease on certain triticale varieties, notably Jackie and Breakwell...

Rust sports readily adhere to clothing... Two further changes in cereal rust pathogen populations have been detected, both in Western Australia... A new pathotype of the barley leaf rust pathogen ( Puccinia hordei ) was detected in WA, based on samples collected in September at Boxwood Hill, Chillinup, Esperance, Kamballup and South Stirling in the state's southern region...
