Morphological and molecular characterization of Derik Halhali olive (Olea europaea L.) accessions grown in Derik–Mardin province of Turkey

The present study was undertaken to validate phenological and morphological differences in the cv. Derik of Mardin province through the use of RAPD markers. The study aimed to examine the relationships between accessions considered to represent cv. Derik Halhali and identify the most closely linked one. The results showed that the Derik Halhali accessions collected from Derik–Mardin province differ at various degrees from the standard Derik Halhali cultivar maintained at Olive Research Institute, Izmir, Turkey. This classification based on RAPD markers could not be related to known morphological information about the accessions.
