Název v původním jazyce

Temporal changes in pathogenicity structure of cucurbit powdery mildew populations

Popis výsledku v původním jazyce

Distribution, disease severity and temporal changes in pathogenicity structure of the two powdery mildew species, Golovinomyces cichoracearum s.l. (Gc) and Podosphaera xanthii (Px), was monitored on cucurbitaceous crops in the Czech Republic (CR) in 2001-2003. Cucurbit powdery mildew was represented by a predominance of Gc and by the sporadic occurrence of Px and corresponded with the early published data. The highest frequency of cucurbit powdery mildews was recorded on Cucurbita pepo and C. maxima (90%, resp. 84 % locations), was very rarely observed on Cucumis sativus (4-5 %). A medium level of disease intensity (25-50 %) occurred on Cucurbita spp. There was proved a high variability in pathogenicity of surveyed cucurbit powdery mildew populations.Altogether 14 different pathotypes (8 Gc, 6 Px) and 79 races (58 Gc, 21 Px) were determined. Isolates virulent to Cucumis melo (line MR-1) and avirulent to C. melo (Iran-H) were found in both powdery mildew species. Occurrence of some hi
