Abstract: Inter-simple sequence repeat(ISSR)molecular markers were applied to analyze genetic diversity and clustering of 48 introduced and breeding olive cultivars. 106 bands were amplified by 11 selected primers,among which 99 bands were polymorphic. Percentage of polymorphic loci was 93.40%,which showed a rich genetic diversity in the collection. Based on Nei’s genetic distances,dendrogram of 48 cultivars was constructed through unweighted pair-group method(UPMGA). 48 cultivars were clustered into 4 main groups. 84.6% of native select and breeding cultivars were clustered into 2 groups and most of introduced cultivars were clustered based on their directly introducing places and main usage. The results will provide references for olive resource utilization and further genetic improving.
