This study was carried out to determine the promising genotypes of medlar (Mespilus germanica L.) grown naturally in the neighborhoods of Tekkeköy district of Samsun province (Turkey) in 2017 and 2018 years. In the study, genotypes with a fruit weight of 15 g and more were selected. In the study 33 medlar genotypes were examined. Weighted Ranked Method was used to determine the promising genotypes by considering fruit weight, fruit flesh content, total dry matter content, soluble solid content and vitamin C content in the examined genotypes. In the first year (2017) fruit weight ranged from 15.08 g to 25.44 g, fruit volume ranged from 14.36 mL to 24.11 mL, fruit flesh rate ranged from 78.63% to 92.41%, total dry matter content ranged from 64.20% to 78.01%, SSC ranged from 8.4% to 17.6%, titratable acidity ranged from 0.50% to 0.98%, vitamin C content ranged from 9.60 mg 100g-1 to 40.0 mg 100g-1; In the second year (2018) fruit weight varied from 15.13 g to 22.15 g, fruit volume varied from 15.51 mL to 23.05 mL, fruit flesh rate varied from 74.03% to 94.45%, total dry matter content varied from 67.25% to 79.24%, SSC varied from 6.8% to 15.9%, titratable acidity varied from 0.27% to 1.34%, vitamin C content varied from 7.0 mg 100 g-1 to 34.0 mg 100 g-1 in the study. As a result of the ‘Weighing Ranked Method’, in the best group has the highest score of three genotypes, 4, 25, and 5 genotypes were identified as promising genotypes in this study.
