This paper describes the results of marker-mediated screening of apple varieties for QTL FBF7 fire blight resistance. We detected at least one marker out of three in 12 varieties (85.7%) and two markers out of three in 5 varieties (35.7%). The target fragments of the studied markers in the Antonovka obiknovennaya and Galarina varieties are missing. Indicating the presence of QTL FBF7 three markers (GE-8019, AE10-375 and CH-F7-Fb1) were identified in the Bylina, Rozhdestvenskoe, Uspenskoe and Charodeyka varieties, which we recommend for use in breeding for E. amylovora resistance.
