Özet

Clavibacter michiganensis subsp. michiganensis (Smith) Davis et al (Cmm) is an important bacterial agent for tomatoes causing destructive disease. The best way to control of this disease is to use resistant cultivars. Unfortunately there has not been developed a resistant variety against the Cmm because the heritability of resistance is quite complex. In this study, the reactions of 78 genotypes including wild accessions of tomato and cultivar types were investigated. Cmm suspension adjusted to 10(7)cfu/ml concentration was injected in the wound for the inoculation. Seedlings were incubated in a climate controlled greenhouse. Disease symptoms were scored seven times during eight weeks by using the 0-4 scale values from inoculation. Three genotypes were showed resistance against the Cmm. S. peruvianum and S. chmielewskii were found as tolerant and S. habrochaites was determined as moderate tolerant. Both of genotypes have great importance as new resistance sources that they don't need embryo rescue like S. peruvianum.
