Five species of white truffle were classified using PCR‐based techniques. RAPD (random amplified polymorphic DNA) fingerprints and specific pairs of primers were used. A RAPD fragment was constant in Tuber borchii Vittad. isolates and polymorphic among the other species. Two molecular markers specific for T. borchii were developed from the sequence of the non‐polymorphic RAPD fragment and from regions flanking the 5′‐3′ ends of a truffle gene. These markers were applied in the identification of T. borchii fruit bodies, mycelia and mycorrhizas, allowing us to monitor the development of this fungus during its entire life cycle.
