Research Note Ten cultivars representing Riesling-type vines and 12 cultivars of the Burgundy family were analyzed by RAPD-PCR. Employing computer programs, similarity degrees were calculated from the RAPD patterns obtained from a set of 20 dekamer primers and used to perform cluster analysis. The Riesling-type cultivars could be differentiated from each other and from the progenitor of a cross Pinot noir x Chambourcin ("Spezial" in Fig.l). With the exception of Aubin blanc, Aubin vert and Elbling white, the Riesling-type cultivars did not show any close relationship. From the Burgundies, Pinot noir, Pinot meunier, Pinot blanc and Pinot gris could not be differentiated. Neither could Chardonnay blanc be differentiated from Chardonnay musque, nor Aligoté from Aligoté vert. Discrimination between the other cultivars was possible. Two Morillon samples from different origins were analyzed and showed clear differences in their RAPD patterns. Furthermore, they seemed to be more similar to Riesling white than to the Burgundies.
