Collaborative project: Improving fungal resistance in maize by combining genetic and molecular resources using precision breeding. Subproject 3 (PRIMA)
Project
Project code: 2818202915
Contract period: 19.05.2017
- 18.05.2020
Budget: 297,629 Euro
Purpose of research: Applied research
The aim of the project was to improve resistance of maize against ear rot (Fusarium spp.) and Northern Corn Leaf Blight (Setosphaeria turcica). Both fungal diseases cause significant yield losses and treats human and animal health. Therefore, new methods for precision breeding for a targeted utilization of tropical genetic resources were developed. Novel and environmentally stable resistance factors from Brazilian donor genotypes were identified using molecular markers. They can be used for marker assisted breeding and genomic selection approaches. Studies on samples from Brazil and Germany revealed that Fusarium species are well adapted to maize as a host in Germany, but S. turcica might increase aggressiveness with increasing temperature. It was shown that callose synthase GSL3 can be used to increase fungal resistance. These finding could help in future to develop novel resistance using genome editing or tilling approaches. The results of the project will be used for the development of innovative maize hybrids with improved resistance.
