Özet

Turkey is one of the most important mulberry fruit producers in the world. In particular, in Eastern and Inner part of Turkey, mulberry fruits are processed into several products such as 'Mulberry Pekmez', 'Mulberry Pestil', 'Mulberry Kome' etc. Therefore, mulberry fruits give higher economic returns thus have greater employment potentials in Turkey. In order to improve the yield and fruit quality through breeding, the genetic variations and relationships among 15 selected white mulberry genotypes (Morus alba L.) were evaluated using Random Amplified Polymorphic DNA (RAPD). A total of 101 DNA markers were generated by 16 random primers, with an average of 6.3 easily detectable markers per primer. Several RAPD markers showed unique patterns of mean frequency that differed among the white mulberry genotypes. The distance matrix showed that the highest genetic distance (0.902) was between EMS13 and EMS8 and the least (0.413) was between EMS12 and EMS15. According to the results, RAPD analysis can be used for the characterization and grouping of mulberry genotypes. The genetically divergent genotypes identified from this study would be of much use in the future breeding program.
