- Abstract
Mediterranean olive cultivars (Olea europaea), including the historic cultivar 'Mehras,' were analyzed using ISSR to identify and study the genetic relationships among them. Three ISSR primers (UBC-807, ISSR 810, ISSR 825) generated 784 data entries (221 for present and 563 for absent bands), which were analyzed using SPSS and Structure software. Results showed that fragment size ranged between 250 to 1700 bp. The similarity among the fourteen cultivars ranged from 10% between cultivars 'Nabali Muhasan' and 'Arbosana' up to 59% between genotypes 'Qaisi' and 'Kafari Baladi.' When primers were evaluated for their discriminating power, it was found that all of them had a value equal to 1. Moreover, the primer PIC values were 0.29, 0.31, and 0.31 for ISSR 807, ISSR 810, and ISSR 825, respectively. The constructed dendrogram showed four main clades, while Nabali Muhasan did not cluster with any. The first clade clustered included five cultivars. The second clade included four cultivars. Both the third and fourth clades included two cultivars each. The genome structure confirms the dendrogram tree.
