CucCAP researchers identify QTL associated with resistance to Phytophthora fruit rot in cucumber
Phytophthora fruit rot is a major disease impacting pickling cucumber production for which there are no resistant varieties. Genomic approaches were performed on the cucumber core collection leading to identification and verification of several quantitative trait loci associated with resistance. The results from this work can be applied to future disease resistance studies and to assist marker-assisted selection in breeding programs.
