Abstract:

The research analyzed the ‘Cabernet Gernischts’ with typical differences collected in Yantai and the surrounding areas and testifies the genetic relation between ‘Cabernet Sauvignon’ and ‘Cabernet Franc’, providing supporting theoretical evidence for the screening of the excellent vinifera clones. By adopting RAPD and PCR technology as well as analyzing the genetic varieties of 8 ‘Cabernet Gernischt’ clones and ‘Cabernet Sauvignon’ and ‘Cabernet Franc’, it can be concluded that there is no discrepancy among E-03, E-04, E-06, E-07and E-08; while difference existed in E-01, E-02 and E-05 to some extent. All clones of ‘Cabernet Gernischts’ were similar to those of ‘Cabernet Franc’, but more different from ‘Caberner Sauvignon’. The screening of ‘Cabernet Gernischt’ can be narrowed down to 4 clones.
