Structure and temporal shifts in virulence of Pseudoperonospora cubensis populations in the Czech Republic

Popis výsledku v původním jazyce

The structure and temporal changes in the virulence of Pseudoperonospora cubensis (causal agent of cucurbit downy mildew) was studied in pathogen populations in the Czech Republic (CR) from 2001 to 2010. A total of 398 P. cubensis isolates collected fromCucumis sativus, Cucumis melo, Cucurbita maxima, Cucurbita pepo, Cucurbita moschata, and Citrullus lanatus were analyzed for variation in virulence (pathotypes) using a differential set of 12 genotypes of cucurbitaceous plants. All isolates of P. cubensis were characterized by their level of virulence (classified according the number of virulence factors, VF; low VF=1-4, medium VF=5-8, high VF=9-12): high (75%), medium (24%) and low (1%). The structure and changes in virulence in the pathogen populations were expressed by pathotypes using tetrade numerical codes and a total of 67 different pathotypes of P. cubensis were determined. In the recent pathogen populations there was prevailing frequency (70-100%) of isolates with high number
