Assessing the Stem Rust Situation in Western Siberia

Up to 2014 wheat stem rust was not considered of major importance in Western Siberia, but severe epidemics in 2015 and 2016 has changed the situation. New research to resolve stem rust epidemiology in the region and additional efforts in breeding for rust resistance is urgently needed.

Definitions of genetic groups and races

Sampling site focus in 2019 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.

MULTIRES: Multiple disease resistance in wheat

The overall goal of this public-private partnership is to improve wheat productivity by reducing losses due to plant disease in conventional and organic farming systems and the dependence of fungicide sprays in general. Part of the solution is the implementation of EU Directive 2009/128/EC (“IPM directive”), which may be a major challenge at the private farm level unless high-yielding, resistant crop varieties are available. This project will utilize two different strategies for developing disease resistant wheat:

  • Multi-parent advanced generation inter-cross (MAGIC) and

  • Nested association mapping (NAM).

New phenotyping methods using microscopy will be applied on new multi-resistant wheat lines emerging from the project in order to assess and evaluate resistance mechanisms and expected ‘durability’ of identified resistance.
