This study was carried out to determine the phenological, morphological, pomological, and yield characteristics of some standard quince cultivars. The earliest flowering occurred in ‘Limon’, and the earliest harvest was recorded in ‘Gördes’ cultivar. There were statistical differences between cultivars and years in terms of the examined characteristics. The highest rootstock diameter was observed in ‘Limon’, and the highest stem diameter was recorded in ‘Gördes’ quince cultivar. In the study, fruit weight varied between 334.91-377.93 g, geometric diameter varied between 86.02-87.26 mm, flesh firmness varied between 11.33-11.71 kg cm-2, TSS content varied between 11.88-12.70 %, pH varied between 3.31-3.62, titratable acidity varied between 0.51-0.62 %. Fruit number per tree, yield per tree, yield per stem cross-section area, and yield per crown volume were higher in ‘Limon’ than in other cultivars. Among the cultivars, fruit number ranged from 33.07 to 51.62 tree -1, yield ranged from 9.82 to 15.41 kg tree -1, yield efficiency ranged from 0.61 to 0.95 kg cm-2, and yield per crown volume ranged from 8.78 to 12.01 kg m-3. Differences between cultivars in terms of L*, a*, and chroma were observed. While, no differences were determined between cultivars in terms of b* and hueo. Among the cultivars, L* value varied from 62.58 to 76.83, the chroma varied from 33.10 to 45.11, and the hueo varied from 111.98 to 115.06. As a result of the study, it can be said that the fruit yield and quality characteristics of ‘Limon’ cultivar were higher than the other cultivars.
