Molecular evaluation of some Iranian mango genotypes using microsatellite markers

Mango is one of the most important tropical fruits, rich of nutrients and good components. That is cultivated in southern region of Iran. Molecular identification of mango genotypes helps in its germplasm management and avoiding misidentification of genotypes. In this study 16 Simple Sequence Repeats (SSRs) primers were used to analyze genetic relationship among 41 mango genotypes. A total of 55 alleles were detected with an average of 3.5 alleles per locus. The number of putative alleles ranged from 2 to 6. Observed and expected levels of heterozygosity ranged from 0.3 to 0.87 and 0.29 to 0.84 respectively. By paring banding patterns obtained from the 16 primers pakistanian and Indian genotypes could be separated. All genotypes with synonym names were placed at different groups, except (ʹKalak 2ʹ and ʹKalak 3ʹ). Totally 18 taxon specific alleles were recorded that mostly belonged to ʹSendreri-2ʹ and ʹLangra-1ʹ
