Fire blight is one of the most damaging diseases in the majority of apple (Malus x domestica) producing countries worldwide. The region of the quantitative trait for resistance to Erwinia amylovora and the same data mapped as single gene in the wild apple Malus x robusta 5 was enriched with additional molecular markers. Generated phenotypic data of individuals that carry a crossing over in the region of interest allowed to position the locus coding for resistance into a short section at the top of linkage group 3 flanked by molecular markers.
