Inwertsetzung pflanzengenetischer Ressourcen des Hafers - ein Beitrag zur Kulturartenvielfalt in der Landwirtschaft
Germeier, Christoph | Herrmann, Matthias
In modern plant breeding programmes genetic variation is often not sufficient to reach certain trait combinations. To guard against such situations, plant genetic resources are evaluated and developed via backcrossing programmes with modern cultivars. In a European concerted action with 15 partners in nine European countries genebank material and current commercial varieties were evaluated for traits considered important for future oat breeding in a European premium market. These are quality traits as protein-, fat- and β-glucan content, avenanthramides, resistance to contamination by mycotoxins and tolerance to cold. Relatively high values for β-glucan content were found in wild A. damascena und A. wiestii accessions. But also within the hexaploid Avena genepool large ranges for each trait were found. Results are documented within the European Avena Database (EADB). The development of genetic resources is demonstrated for powdery mildew resistance and the β-glucan content.
