Abstract
Botrytis cinerea has been reported as a species complex containing two cryptic species, groups I (Botrytis pseudocinerea) and II (B. cinerea sensu stricto). In order to compare the pathogenicity of group I and group II of B. cinerea, we have selected 4 strains of group I and 4 strains of group II. The results demonstrated that competitive infection of group II was more on grape, cucumber and paprika leaves, than group I. However the results on bean leaves did not correlate the applied B. cinerea group.
Highlights
The lesions on grape leaf following the mycelial discs of group I (8001, 8005) and group II (8020, 8025) isolates placed on the leaf and incubated at 18°C for 3 days in a humid, dark chamber
The lesions on paprika leaf following the mycelial discs of group I (8005, 8032) and group II (8025, 8034) isolates placed on the leaf and incubated at 18°C for 3 days in a humid, dark chamber

Summary
Ezek nem egyeznek meg a korábbi, transzpozonok jelenléte alapján felállított csoportokkal, mert mind a korábban I-es csoportként elnevezett Botrytis pseudocinerea, mind a II csoportba tartozó B. cinerea sensu stricto izolátumok között megtalálhatóak mind vacuma, mind transposa típusba tartozó törzsek, valamint a csak egyik transzpozont tartalmazó típusok is (Fournier et al, 2005; Ma and Michailides, 2005; Váczy et al, 2008, Fekete et al, 2009, Walker et al, 2011). Eddigi tanulmányok alapján a II csoportba tartozó B. cinerea van döntő mértékben jelen a fertőzött növényekről származó mintában (Fournier et al, 2005.; Martinez et al, 2005; Váczy et al, 2008, Fekete et al, 2009, Walker et al, 2011).
