Hybridization of minisatellite DNA with an M13 probe yields DNA fingerprints that usually are highly cultivar-specific. However, 15 different sports of `Red Delicious' apples (Malus × domestics Borkh.) exhibited almost identical fingerprints. The mutations determining the morphological differences between the sports could not be detected by the minisatellite probe. These hypervariable DNA sequences appear rather stable in apples, making them ideal for differentiating between cultivars derived through genetic recombination but probably not very useful for differentiating between vegetative sports.
