Summary Amplification profiles of the M13 minisatellite core sequence from 47 isolates of Heterobasidion annosum s.l ., collected mostly from Abies alba in different European countries, were analysed in comparison with profiles of four isolates of H. annosum s.s. and three isolates of H. parviporum . Genetic variation within and among groups of populations was studied by analysis of molecular variance. A dendrogram constructed with the Neighbor‐Joining method differentiated the three species from each other. Isolates of H. abietinum from Balkan peninsula, Italian peninsula and French Pyrenees each separated into clusters according to geographical origin. Such clear geographic clustering was not detected among isolates from central Europe. The variations between H. abietinum isolates in relation to the migration history of Abies are discussed.
