Bacterial canker of tomato, caused by Clavibacter michiganensis subsp. michiganensis (Cmm), is considered the most serious bacterial threat in tomato and causes large damages in production areas. Worldwide, Cmm is subjected to quarantine regulations. There is no cultivar on the market containing Cmm resistance. A mapping study was done in order to identify Quantitative Trait Loci (QTL) for resistance in a cross between Solanum lycopersicum and S. pimpinellifolium GI.1554, a wild relative of tomato. Besides wilting, symptoms like stem discoloration and bacterial titer were considered. Using single trait and multi-trait approaches, we have identified five QTL regions that are associated with wilting, stem discoloration and bacterial titer in three different environments. These QTLs can be used in breeding programs to develop cultivars with higher levels of resistance.
