Abstract:

The genetic diversity analysis of the 6 kinds of ‘Cabernet’, which were planted in grape growing areas of Yantai, was made by RAPD and SSR techniques for clearing the phylogenetic relationships of the wine grape strains of ‘Cabernet Gernischt’ and other ‘Cabernet’ strains, and for further selecting the fine wine grape. The results showed that the 6 kinds of ‘Cabernet’ could be divided to two groups in the phyogenetic tree. Although the inheritances of the 4 kinds of ‘Cabernet Gernischt’ were different from the ‘Cabernet Sauvignon’, or from the ‘Cabernet Franc’, the 4 kinds of ‘Cabernet Gernischts’ were not fallen under one group. We guess that the ‘Cabernet Gernischts’ might be the strain obtained by characteristic selection from the ‘Cabernet Franc’. The gather of the ‘Qixianan Cabernet Gernischt’ and the ‘Xingfu Cabernet Gernischt’ offer a basis for selecting the excellent grape strains.
