Özet
Fusarium wilt, caused by Fusarium oxysporum f. sp. melonis (F.o.m), is a soil-borne disease of melon (Cucumis melo L.). Fusarium oxysporum f. sp. melonis (F.o.m) causes serious economic losses in melon. Two dominant resistance genes have been identified, Fom-1 and Fom-2, which provide resistance to races 0 and 2, and races 0 and 1, respectively. The most effective control measure is the use of resistant varieties. We mainly tested 44 local melon local varieties from Egean region and different parts of Turkey to determine their resistance to Fusarium wilt with artifical inoculation (Races FOM 0, FOM 1, FOM 2, FOM 1,2 pathogen isolates inoculated to melon seedlings roots) and for Fom1 and Fom2 genes using SCAR (Sequence Characterized Amplified Region) and CAPS (Cleaved Amplified Polymorphic Sequences) molecular markers. Results of artifical inoculation tests and molecular markers tests for race FOM 2 were not consistent. According to morphological and molecular results, we were able to detect some resistant varieties for race FOM 0 and FOM 1. These varieties are: TR-40559 (Malatya, var. cantalupensis), TR-70699 (Manisa, var. inodorus), TR-61613 (Mugla, var. inodorus) and TR-69891 (Kirkagac, var. inodorus). It can be stated that these varieties are usable in future fusarium wilt resistant breeding programs.
