CucCAP scientists identified candidate gene contributing to resistance to downy mildew in cucumber
Downy mildew (DM) is an important disease of cucumber and other cucurbits. Many quantitative trait loci (QTL) have been identified from different resistant resources but very few have been fine mapped or cloned. CucCAP researchers in USDA-ARS and the University of Wisconsin Madison reported identification and functional characterization of the candidate gene for the major-effect QTL, dm5.3, for DM resistance from the plant introduction line PI 197088. This gene, which can enhance plant disease signaling, is currently being used to breed for disease resistance in cucumber.
Planting Cucumbers Early to Avoid Downy Mildew
Downy mildew affects cucumber crops in South Carolina every year and can cause huge crop losses. Clemson University researchers say planting early can cut growers’ losses.

CucCAP Cucumber team members made virtual presentations at the 2022 Plant and Animal Genome meeting in January 2022.
2021 CucCAP Cucumber Team Publications and Presentations
Cucumber Team | 2021 Progress Report
The CucCAP Cucumber Team is led by Yiqun Weng. Team objectives are to develop genomic, bioinformatic, mapping approaches and tools for cucurbits, map and develop markers for disease resistance, and QTL introgression into breeding or advanced lines, and release to breeders.
