Recent studies have suggested that the resistance of apple trees to GLS is controlled by a recessive gene called Rgls. This study investigated whether EPAGRI new apple cultivars have this resistance gene. The cultivars evaluated were ?Fuji Suprema? and ?Gala Real?, which are standards of resistance and susceptibility to GLS, respectively, and the new apple cultivars selected by the phenotypic resistance to GLS: ?Monalisa?, ?Luiza?, ?Venice?, ?Isadora? (hybrids) and ?Gala Gui? (spontaneous 'Gala' mutant). The DNA of cultivars was extracted and amplified using the SSR aColletotrichum spp agenetic resistance amolecular markers1 aARGENTA, L.
