Apple is one of the most produced fruit crops in the world with over 86 million tons of production. Today, domesticated apple (Malus domestica Borkh.) is cultivated over a large geography, from the cold sections of Siberia to the temperate sections of Ecuador. Apart from Malus domestica, various apple species such as Malus sieversii, Malus niedzwetzkyana, Malus kirghisorum are found as natural populations, especially in Central Asia. Although morphological markers have been used to determine the genetic similarities/differences of plant species and varieties, in recent years, the use of molecular markers supporting morphological markers has become widespread. One of the commonly used molecular markers is the SRAP marker system. Like in other species, SRAP markers are used in determining genetic diversity in apples as well. In this study, the genetic similarities/differences of 9 genotypes belonging to 4 different apple species were aimed to be determined using the SRAP marker system. As a result of the study, two main groups were formed, with Malus niedzwetzkyana and Malus kirgishorum species in the first group, and Malus domestica and Malus sieversii species in the second group. The genetic similarity ratio varied between 0.450 and 0.975.
