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.
RustWatch - developing a European early warning system for wheat rust diseases
The overall concept of the project is to seek European solutions to solve challenges caused by wheat rust disease (yellow-, leaf- and stem rust) - emerging pathogens which spread across national borders and affect major food crops in EU member states. This involves inter-disciplinary collaboration between plant pathology, breeding, agronomy, agro-chemistry, molecular genetics and Information and Communication Technologies (ICT), i.e., to increase the expertise and efficiency in rust monitoring within these stakeholder networks. Research activities will interact at all these steps and will involve two-way communication with stakeholders, recognizing their expertise to resistance breeding, disease surveillance and pathogen sampling. IPM-based disease management will involve project partners as well as larger lead users by linking with pre-existing stakeholder networks within plant breeding, value-for-cultivation-and-use (VCU) trials, agricultural advisory services and the agrochemical industry
Development of the European early warning system for wheat rust is based on a multi-actor approach, which takes into account new knowledge about drivers for spread and establishment of new rust races and their implications for disease prevention and control. The system will enable access to shared facilities and it will be adopted and validated in 5 case study regions.
