- Inter-simple sequence repeat (ISSR) markers were employed to detect the genetic diversity among 70 grape accessions including 52 clones of 17 Chinese wild grape species, seven interspecific hybrids, 10 Vitis vinifera L. cultivars, and one strain of Vitis riparia L. A total of 119 polymorphic bands with an average of 11.9 per primer were observed. The unweighted pair-group method (UPGMA) analysis indicated that the 70 clones or accessions had a similarity range from 0.08 to 0.93, indicating that abundant diversities exist among these accessions. Based on cluster analysis and principal coordinate analysis, all accessions could be divided into two major groups, the Chinese wild grape group, and the American and European cultivar group. The largest distance was found among V. riparia MichX, Vitis piasezkii, V. vinifera L. interspecific hybrid (Vitis binifera × V. labrusca) and the wild grapes native to China.
