Özet

Melon (Cucumis melo L.), a prominent member of the Cucurbitaceae family, is one of the most widely

cultivated crops globally. Its broad native range has led to extensive genetic diversity. Among its

many varieties, the fragrant Pocket Melon (Cucumis melo spp. melo var. dudaim), known as Şamama

in Turkish, is a heritage treasure originating from the ancient lands extending from Turkey to

Afghanistan. This captivating melon variety, with its unique aroma and medicinal properties, has

intrigued scientists and growers for centuries. Its history dates back to the earliest civilizations, and

its uses are quite diverse. To understand its genetic differences and preserve emerging new varieties,

molecular studies are essential. This research morphologically analyzed Şamama genotypes collected

from various regions. In addition, it aimed to determine the genetic relationships between these

genotypes, some Şamama genotypes obtained from domestic and international sources, and other

widely grown melon varieties. This determination was based on both fruit characteristics and

molecular methods, such as iPBS. The Şamama genotypes studied showed a wide variation in fruit

weight, length, rind and flesh thickness, total soluble solids (TSS), and pH values. The morphological

data revealed significant differences among the genotypes in terms of marketability, consumer

preference, and local adaptation. Molecular analysis with iPBS markers yielded a total of 32

polymorphic bands, and the average polymorphic information content (PIC) was calculated as 0.416.

These results indicate that the Şamama genotypes possess a moderate level of genetic diversity, with

a high degree of concordance between their genetic structure and morphological traits. Cluster

analysis showed that the genotypes grouped according to their geographical origin, while some

samples distinctly separated, suggesting they represent potential genetic resources. Overall, the findings

demonstrate that the Şamama genotypes from the Lake Van Basin have rich genetic

diversity, highlighting their significant potential for both the conservation of genetic resources and

for use in future breeding programs.
