Collaborative project: Genetic analysis and modeling of wheat-rust interaction to develop stable, multi-resistant wheat varieties - subproject C (RustHealth)
Project
Project code: 281D120C21
Contract period: 01.09.2023
- 31.08.2026
Budget: 206,515 Euro
Purpose of research: Applied research
Keywords: plant diseases (virusus, bacteria, fungi, phytoplasma), wheat, crop production, modeling, climate change adaptation, resistance
The aim of RustHealth is to gain a deeper understanding of plant-pathogen interactions for yellow and leaf rust in wheat. This enables the sustainable use of resistances for stable wheat production with reduced crop protection and represents an important contribution to the implementation of the "Green Deal". On the other hand, a library of stem rust resistance donors will be established and genetically characterized. This is a prerequisite for being able to react quickly with resistance breeding to a disease spectrum that has changed due to climate change. The RustHealth research project builds on the comprehensive wheat population that will now be selectively expanded to better cover the genetic spectrum of the resistance spectrum of the varieties currently in use. The lines will be evaluated in very extensive field trials for yellow, leaf and stem rust resistance and specifically for individual isolates in the macrophenomics platform. In addition, isolates will be collected for yellow and leaf rust in the individual field trials. These will be sequenced and region-specific be/ent rust races and their frequency distribution identified. The data will be analyzed in biometric models integrated with other environmental parameters to understand and predict the genetic architecture of genotype_Wheat × genotype_Pathogen × environment (G×G×E) interactions. As a result, gene stewardship, i.e., rules for long-term use of resistance genes, will be elaborated as a model for rust diseases in wheat. The principles to be worked out are relevant and transferable not only for wheat but also for other crop species and pathogens.
