Genetic relationship of some olive cultivars grown in Syria by using SSR Technology

Abstract

This study was carried out during the period of 2017-2018 aiming to study genetic relationship for seven olive cultivars grown in the Coastal Area of Syria. We used 21 pairs of Simple Sequence Repeats (SSR) markers. The total markers produced 58 alleles with an average of 2.76 allele per locus, number of alleles generated SSR markers, and the number of SSR markers per primer pair ranged from 1 to (UDO99-027 -UDO99-026- DCA18), 6 alleles (for one marker DCA3).

Polymorphic information content (PIC) values ranged from 0.2149 (UDO99-027-UDO99-031) to 0.7913 DCA3 with an average 0.3907. Genetic diversity (GD) ranged from 0.103 (UDO99-031) to 0.755(UDO99-008) with an average 0.488. The results of cluster analysis and dendrogram discriminated all genotypes and clustered them separately into three major groups. Group I: Dab1, group II: KHODEIRI, DOEBLI, Dab 2, SUKARY, AYRONY, groups III: FRONTOYO. The results confirmed the ability of SSR markers to be used for the determination of genetic diversity among the olive verity.
