Özet

Seventy isolates of Fusarium oxysporum (Schlechtend: Fr.) f. sp. melongenae Matuo and Ishigami (Fomg), the causal agent of eggplant Fusarium wilt, were tested for their interaction with different lines and cultivars to determine whether there was race-specific interaction. Also, a total of 13 cultivars were tested under greenhouse conditions to evaluate the presence of resistance to Fusarium wilt. The disease severity (%) and the area under disease progress curve (AUDPC) for each of the Fomg isolates were calculated by scale values. Results showed that neither of the resistant lines (LS1934 and LS2436) exhibited wilting symptoms, whereas susceptible local cultivars (cvs. 'Kemer' and 'Hadrian') displayed severe disease symptoms. There was no significant variation in the virulence, indicating the occurrence of a race or races among 70 Fomg isolates tested on resistant lines and susceptible cultivars. This may indicate a genetically homogeneous population structure of Fomg in Turkey.
