Collaborative project: Strategies to protect cereals from the climate induced increase of fungal diseases - subproject 1 (GetreideProtekt)
Project
Project code: 281B202016
Contract period: 01.09.2018
- 31.01.2022
Budget: 385,381 Euro
Purpose of research: Applied research
Keywords: cereals, wheat, triticale, yellow rust, Fusarium head blight, resistance breeding
The present project established an early warning system as well as a marker-supported monitoring for yellow and stem rust providing farmers, advisors and breeders with up-to-date information about the occurrence of rust. Model tests on the effectiveness of fungicides with regard to cultivar resistance, time of application, application rate and temperature showed that highly effective fungicides with different groups of active ingredients are available. The resistance of wheat and triticale to stem rust, yellow rust and Fusarium head blight showed significant genetic variance with high heritabilities. Stem rust resistance of wheat is based on three known resistance loci (Sr24, Sr31, Sr38). Yellow rust resistance was caused by a combination of major genes and QTL. Resistance to Fusarium head blight was based on multiple loci with small effects. Five resistance loci have been identified for the inheritance stem rust resistance of triticale. In combination with highly effective variety resistance, it will be possible in the long term to protect German cereal cultivars from rust diseases and to meet the requirements of integrated plant protection.
