Race analysis of Stem rust at GRRC

Please find GRRC reports:

Samples of stem rust infected wheat from Italy. November 2016

CAUTION: Risk of wheat stem rust in Mediterranean Basin in the forthcoming 2017 crop season following outbreaks on Sicily in 2016

    Disease notes:

    Emergence of Virulence to SrTmp in the Ug99 Race Group of Wheat Stem Rust, Puccinia graminis f. sp. tritici, in Africa / Plant Disease February 2016, Volume 100, Number 2, Page 522

    First Report of the Ug99 Race Group of Wheat Stem Rust, Puccinia graminis f. sp. tritici, in Egypt in 2014 / Plant Disease April 2016, Volume 100, Number 4, Page 863

     

     

     

    Race analysis of Yellow rust at GRRC

    Please find reports of the non-European Puccinia striiformis race analyses activities at GRRC 2010 - 2015:

    Sampling site focus in 2017 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) and now continued in the Delivering Genetic Gain in Wheat project (DGGW), 2016-2020. GRRC can only process samples according to available space and resources at any time, and we cannot guarantee to process all samples received.

    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.
