Abstract: This study was conducted to estimate genetic relationships and natural somatic mutations among selected banana genotypes from different region of Turkey via SRAP molecular markers. Ninety-six banana genotypes including 39 ‘Dwarf Cavendish’, 18 ‘Grande Nain’, 28 ‘Azman’ and 11 other bananas were evaluated. A total of 102 bands were obtained from 19 SRAP primer combinations and 86 (85.5%) of them were polymorphic. Number of bands per primer combination was 5.3 whereas
polymorphic bands per primer combinations were 4.5. Genetic similarity of 96 accessions varied between 0.63–1.00. It was determined genetic variation among the accessions which may allow new selections for breeding programs. Considerable variation was also found among genotypes within the same banana cultivar and it was very important for banana breeding and germplasm evaluation. It can be concluded that SRAP markers could readily be used to estimate genetic relationships among banana genotypes and natural somatic mutations.
