Patterns produced by RFLP analysis of genomic DNA extracted from nine Berlandieri ∞ riparia rootstock cultivars were compared. Of the six grape DNA probes used, several combinations of three probes were sufficient to clearly distinguish all nine rootstocks. Calculation of a similarity index for each pair revealed that 420 A was notably distinct from the other members of the group (D=0.56 compared to an average similarity of 0.77 among all the hybrids), while the Teleki hybrids (SO 4, 5 C, 5 BB, 125 AA, Cosmo 2, Cosmo 10) were generally very similar to each other (average D=0.85). No differences were observed between 5 A and 5 BB, consistent with previous reports that at least some 5 A vines are identical to 5 BB.Downloads
