Downy mildew of cucumber (Cucumis sativus L.), caused by Pseudoperonospora cubensis (Berk. et Curt.) Rostovzev, is one of the most important foliar diseases of cucurbit crops. Two parental lines resistant PI 197085, susceptible PI 175695 and their F2 generation were used in our study. Inheritance of resistance to Pseudoperonospora cubensis in PI 197085 was quantitative. JoiMap 4.1 and MapQTL 6.0 software was used for a linkage groups construction and QTL mapping. Three QTL were detected: DM1, DM2, DM3. The loci were mapped on chromosome 5 of cucumber genome. Molecular analysis confirmed results of classical quantitative genetics indicating that resistance to Pseudoperonospora cubensis in PI 197085 is polygenic trait.
