Abstract
Among various fungal diseases of cultivated roses, powdery mildew and black spot are the economically most important ones in greenhouse and field production. Resistance breeding is an increasingly important alternative to chemical plant protection. We therefore used different approaches to characterise naturally occurring resistance to these diseases. Through extensive genetic analysis with monoconidial isolates of both pathogens in segregating populations three dominant resistance genes could be detected. Using molecular markers these loci could be mapped in the rose genome and in one case tagged on a BAC contig. We also describe the evaluation of additional loci, harbouring putative resistance genes, by mapping rose resistance gene analogues (RGAs) onto the rose chromosome map and in relation to known resistance genes.
