We previously reported that homologues of the VMC8g9 marker
could be distinguished in a different M. rotundifolia×V. vinifera
BC5 hybrid progeny when electrophoresed in high-concentration
agarose gels (Molnár et al., 2007). This method has the advantage of
not requiring the polyacrylamide electrophoresis, the ALF Express
apparatus or the fluorescent labeling of primers.
