ABSTRACT: In this study, variation and inter-relationship of 31 olive cultivars (seven Iranian and 24 foreign cultivars), collected in a germplasm in the north of Iran, were analyzed using Inter Simple Sequence Repeat (ISSR) markers. Nine primers were used for allele scoring. In total, 44 ISSR polymorphic alleles were detected. Cluster analysis of the ISSR data showed inter-cultivar variation for Mediterranean cultivars of Italy, Spain and Greece and they were clearly distinct from the Iranian and Syrian cultivars. The principal coordinate analysis (PCoA) explained 22.55% and 20.78% of the total variation along the first (PC1) and second (PC2) component, respectively. In general, the PCoA plot revealed same affinities for the cultivars as the phylogenetic tree. The outcome of this study could be useful for construction of a molecular database of the cultivars which can be used in breeding and cultivar improvement.
