Collaborative project: Genetic improvement of resistance to ear fusariosis in early maturing maize by QTL mapping in multi-line crosses – Subproject 2
Project
Project code: 2814300207
Contract period: 15.02.2008
- 30.04.2011
Budget: 131,863 Euro
Purpose of research: Experimental development
Ear rot caused by the fungus Fusarium graminearum, is an important disease in maize resulting in contamination of the grain by mycotoxins, mainly deoxynivalenol (DON) and zearalenone (ZEA). Resistant cultivars are the best option for controlling this disease. Aim of this study was to identify genomic regions (QTL, quantitative trait loci) with effect on disease resistance by molecular markers. We detected several QTL for improved resistance and reduced mycotoxin content for DON and ZEA, respectively. Correlation between line and testcross performance was weak. This study illustrates, that the resistance should best be improved by a combination of classical and marker-based selection. In conclusion, the results are a good basis for improvement of ear rot resistance in maize.
