Özet

Turkish Kırkağaç type melon is one of most grown melon in Turkiye because of its well-known taste. The Kırkağaç melon cultivars have several threats during their production including soil borne fungal diseases. Fusarium oxysporum fsp. melonis (FOM) is a soil borne fungal pathogen causing serious wilting, necrosis on plant leaves than plants deaths occurring. The aims of this study is to isolate the Fusarium wilt pathogens from infected Kırkağaç melon plants. For the isolation of Fusarium pathogens, infected Kırkağaç melon plants are collected either field or greenhouse growing areas with guided-statistical sampling method. The 100 samples collected are brought to laboratory, their infected root and stems are surfaced-sterilized and placed on Potato Dextrose Agar (PDA). Fungal colonies are sub-cultured and purified on PDA then they are identified with pathogenicity tests and light microscopy. There are four races (0, 1, 2, and 1.2) defined based on their phenotypic reactions with our melon accessions. The FOM race 1.2 is the most virulent and yield-limiting race found with causing severe wilting and deaths on infected melon plants. The other three races are less virulent than race 1.2 resulting several yellowing, necrosis and wilting on melon cultivars. The identified four races of FOM are long-term stored in cryotubes for further breeding, marker assisted selection and biotechnology studies.
