Re-emergence of stem rust on wheat in Western Europe
In a commentary in Communication Biology, published 4th February 2019, scientists evaluate the risks of re-emergence of wheat stem rust in Europe. In general, the wheat rust “problems” in Europe have been addressed via multiple national initiatives, but in 2018, a new EU H2020 research and innovation program was launched, dealing with all three…

Severe epidemics of wheat yellow rust in Argentina
In 2017, Argentina faced the worst epidemics of yellow rust since the 1930s. Based on samples collected at 22 epidemic sites in September, the Global Rust Reference Center (GRRC) has identified at least three distinct yellow rust genotypes. Two of these were identical to genotypes first detected in Europe and North Africa in 2015-16.

GRRC annual report on wheat yellow rust 2017 released
Unusual and severe epidemics of yellow rust were observed on several continents in 2017. In a number of cases, epidemic sites at different continents were inter-related by prevalence of genetically identical yellow rust genotypes and races.

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.
Funding
The project is funded by Innovation Fund Denmark
Duration: 2015-2020. Research Education: 2 ph.d. and 2 postdocs
