Genetic diversity was assessed using 10 different SSR primers, resulting in a total of 79 polymorphic bands. The CUESTSSR02 primer was the most efficient one with high values for Polymorphic Allele Number (PA), Polymorphic Information Content (PIC), Expected Heterozygosity (He), and Marker Index (MI). Genetic relationships between genotypes were analyzed and visualized using a circular phylogenetic tree, PCoA, and a heatmap. The findings revealed that the local populations are genetically distinct from both registered cultivars and Indian genotypes. Notably, the Akören genotype was identified as genetically isolated from all other genotypes. This study highlights the crucial role of local populations in preserving and enhancing genetic diversity. The integration of Indian genotypes with local populations may contribute to the development of more resilient and productive cultivars. The findings emphasize that the effective use of genetic resources can support sustainable agriculture and improve agricultural performance.}, number={2}, publisher={Hatay Mustafa Kemal Üniversitesi}
