Cucumber Breeding, Genomics, and Pathology
The CucCAP cucumber team is breeding cucumbers for resistance to Downy mildew and Phytophthora fruit rot. In the past five years, CucCAP scientists have identified new sources of resistance for Phytophthora rot in cucumber. QTL or markers were published for Powdery mildew, Downy mildew, angular leaf spot and anthracnose in cucumber. QTL identification and marker development is in progress for Phytophthora rot in cucumber. Transfer of resistances into commercially useful material is underway for Downy mildew and Phytophthora rot in cucumber. Integrated disease management trials will be conducted on new varieties at multiple locations, under different environmental conditions, production practices, and pathogen populations in collaboration with the Integrated Disease Mangement team.
Dr. Weng is a Research geneticist and the Cucumber Team leader.
