Abstract

A genomic remnant of Malus floribunda clone 821 introgressed into the cultivated apple M. x domestica Borkh. was identified using randomly amplified polymorphic DNA (RAPD) markers obtained by the polymerase chain reaction (PCR). Using a set of 59 oligonucleotide decamer primers, polymorphic DNA markers were identified among three pooled DNA samples. Based on the presence or absence of bands among bulked apple scab-resistant selections and cultivars, bulked scab-susceptible cultivars, and a M. floribunda clone 821 sample, one primer, A 15, identified amplified fragments in the scab-resistant bulked sample that was also unique to the M. floribunda clone 821. The unique band from M. floribunda clone 821 was amplified in four out of 17 scab-resistant selections/cultivars. This RAPD, designated OA15₉₀₀, identifies an introgressed fragment that has as yet no known function.
