Abstract
Cappadocia region of Anatolia hosts the third largest wild apricot population in Turkey. The objective of the study was to characterize 44 wild apricot genotypes selected from Cappadocia Region (Nevşehir-Turkey) as prominent with their late flowering, resistance to spring late frosts, large fruit sizes and/or late fruit ripening characteristics and 5 reference apricot cultivars (‘Hacıhaliloğlu’, ‘Kabaaşı’, ‘Hasanbey’, ‘Aprikoz’ and ‘Levent’) with SSR (simple sequence repeats) markers. A total of 16 SSR primers were used and 13 of them were successfully amplified. Total number of alleles was 107, average number of alleles was 8.23; average He and Ho values were 0.722 and 0.669, respectively. Polymorphism information content (PIC) values varied between 0.471 and 0.845. There was a quite high genetic diversity among wild apricot genotypes that genetic similarity values varied between 12 and 96%. Homonymous and synonymous genotypes were not encountered.

Considering the success ratios of 16 simple sequence repeats (SSRs) loci selected for genetic characterization of wild apricot types, 10-15 of them were thought to be used in genetic analyses
Summary
Vavilov (1951) indicated the origin centers of culture apricots (Prunus armeniaca L.) as China, Central Asia and defined Near-East centers extending from Northeastern Iran to Caucasus and Central Anatolia as the secondary origin center of cultured forms. Kostina (1969) divided P. armeniaca species into 4 large eco-geographical groups and 13 regional subgroups and placed Turkey into Iran-Caucasus ecogeographic group (Layne et al 1996; Zhebentyayeva et al 2012). Anatolia (Turkey) is located within the secondary origin center of apricots, has a great genetic diversity (Ercisli 2004). Nevşehir province is located right at the center of Cappadocia region of Anatolia, and the province hosts the 3rd largest wild apricot population with about 145000 trees (TUIK 2017). This population is characterized with late flowering, resistance to spring late frosts, large fruits and late ripening. The population exhibits a large variation in fruit physical and quality attributes. Such a diverse population was evaluated for the first time by Dumanoğlu et al (2018) within
