Long-lasting (2001 to 2009) Variation in Virulence among Czech Cucurbit Powdery Mildew Populations Screened on Eleven Cucumis melo Differential Genotypes

Original language description

The virulence structure of the cucurbit powdery mildews (CPM), Golovinomyces orontii s.l. (Go) and Podosphaera xanthii (Px), was studied on a set of 504 isolates (373 Go and 131 Px). CPM isolates originated from different Cucurbitaceae host species, sampled in various geographical areas of the Czech Republic in the years 2001-2009. They were screened on a set of 11 Cucumis melo differential genotypes (Iran H, Védrantais, PMR45, WMR29, Edisto 47, PI 414723, PMR5, PI 124112, MR-1, Nantais Oblong, Solartur). Since the year 2005, C. melo genotype PI 313970 has been also tested. Seven differentials and also PI 313970 exhibited a broad resistance variation to both CPM species when compared with the otherfour differentials (Iran H, Védrantais, Nantains Oblong, Solartur) which were highly susceptible. Altogether, 114 different reaction patterns in Czech CPM populations were observed using a differential set of 11 C. melo genotypes (old standard set; see Lebeda et al. 2011). There were also noted differential responses to PI 313970 among screened CPM isolates. Isolates virulent to line MR-1 but avirulent to Iran H were found in both CPM species. Differences in virulence variation were found between and within both CPM pathogens, as well as among the studied years and areas. There were substantial differences in the frequencies of low, medium and highly virulent CPM strains. Medium and highly virulent strains prevailed mostly in Czech CPM populations, with the exception of 2006 when strains with low virulence occurred in more than 50% of the cases in both CPM species.
