Race analysis of Puccinia striiformis at GRRC
Please find reports of the non-European Puccinia striiformis race analyses activities at GRRC 2010 - 2015:
- Summary of Puccinia Striiformis race analysis 2015 NEW February 2016
- Summary of Puccinia Striiformis race analysis 2014
- Summary of Puccinia Striiformis race analysis 2013
- Summary of Puccinia striiformis isolate pathotyping 2012
- Summary of Puccinia striiformis isolate pathotyping 2011
- Summary of Puccinia striiformis isolate pathotyping 2010
Sampling site focus in 2014 will be selected by staff at ICARDA, CIMMYT and NARCs in Africa and Asia, with a focus on high risk epidemic areas. Since 2011, GRRC also accepted samples of stem rust (Puccinia graminis tritici) as agreed upon with the Borlaug Global Rust Initiative and the phase II of the Durable Rust Resistance in Wheat Project (DRRW). GRRC can only process samples according to available space and resources at any time, and we cannot guarantee to process all samples received. This report deals only with yellow rust. Submission procedures are enclosed at the end of the report, 2012.
RUSTFIGHT - Meeting the new challenges from infectious rust fungi on crop plants
The Danish Research Council for Strategic Research is contributing 19.8m DKK to a new research project to be led by Aarhus University. The results from the project will bring more knowledge to the prevention and control of wheat rust.
The research will be a collaboration between The Global Rust Reference Centre at Aarhus University, University of Copenhagen, Technical University of Denmark, Sejet Planteforædling and leading international institutions.
In the project the scientists will try to decode how and why the fungus starts to develop so aggressively. They will also prepare a list of the genetic codes of the fungus – the so-called effectors – that are responsible for the ability of the fungus to adapt to new wheat varieties. These effectors will be screened and used to develop wheat cultivars with durable rust resistance.
Another ambition is to track down rust resistance in resistant wheat varieties and strains made available from international institutions to Danish plant breeders.
