The objective of this study was to determine the pomological traits of selected medlar (Mespilus germanica L.) types and interrelationships among these pomological traits. This research was carried out on medlar types grown in the coastal area of Ordu, Giresun, Trabzon and Rize Provinces in the Middle and East Black Sea Region of Turkey in 2000 and 2001. In this study, fruit weight was correlated with calyx basin width, calyx basin length, fruit width, fruit length, fruit volume, seed weight and seed volume, and total soluble solids was correlated with fruit length, seed weight, seed volume, pH, malic acid and total dry matter. Large positive correlation for fruit weight with fruit volume, and large positive correlation for total soluble solids with total dry matter was obtained. Fifteen medlar types were selected. In selected medlar types, fruit weight, seed weight, total soluble solids and total dry matter ranged from 16.51 g to 32.98 g, from 0.23 g to 0.68 g, from 13.00 % to 26.00 % and from 18.54 % to 38.07 respectively.
