ResumoSummaryIn this study, genetic diversity among 48 Iranian apple genotypes was determined using simple sequence repeat (SSR) markers. Sixty-six alleles were generated at 15 SSR loci. The mean number of alleles per locus was 4.4. A similarity matrix based on Jaccard’s coefficients for all 48 apple genotypes gave values from 0.02 – 0.68, which indicated a broad genetic base. The maximum similarity (0.68) was observed between the genotypes ‘Shahrood’ and ‘M2’. The lowest similarity (0.02) was observed between the genotypes ‘Azayesh’ and ‘Shemiran’. Based on a principal co-ordinates analysis and an unweighted pair-group method using arithmetic average (UPGMA) clustering algorithm, three distinct groups were established. The local genotype, ‘Gami-Almasi’, which was the most dwarf Iranian native apple rootstock, was placed in a separate cluster with a low level of similarity to both other groups.
