Özet
In the 2007 and 2008 melon growing seasons, surveys were conducted in Adana, Antalya, Hatay and Mersin provinces of the Mediterranean Region and Adiyaman, Batman, Diyarbakir, Mardin, Sanliurfa provinces of south-eastern Anatolia Region of Turkey. One hundred and fourteen F. oxysporum isolates were recovered from diseased melon plants. The pathogenicity was tested on melon seedlings at the one-true-leaf stage. Eighty-nine of the 114 isolates of F. oxysporum were virulent on melon seedlings. Based on disease symptoms, 89 isolates were identified as F. oxysporum f. sp. melonis (Fom). Mutants in different phenotypic classes were paired on MM. Of 89 Fom isolates, 71 79% were found belonging to VCG 0138, 13 15% and 5 (6%) to VCG 0134 and 0133, respectively. All strains were vegetatively self-compatible. Fom isolates were grouped into three distinct clusters and eight F. oxysporum isolates grouped into one cluster. Group one included all eight F. oxysporum isolates obtained from pea plants. Group two included 14 isolates belonging to VCG 0134, group three included 57 Fom isolates belonging to VCG 0138 and five belonging to VCG 0133. Groups two and three composed of race 0 and 1, whereas group 4 contained only race 1-2.
