Development of Powdery Mildew Resistant Markers for Cucumber Nolecular Breeding Program in Korea

The powdery mildew is one of the most devastating leaf disease of cucumber in Korea. After the successful hybridization between breeding lines of cucumber (C. sativus L.), a mapping population for QTL mapping of powdery mildew resistance has been generated. For this purpose we are setting up the stable method to give rise powdery diseas in cucumber. Based on this inoculation method, we are performing classical QTL mapping and candidate gene approach using the mapping population and divergent resistance germplasms.
