In this study, agro-morphological properties, phenoliccompounds,and organic acid contents in the fruits of service tree (Sorbus domestica L.) genotypes naturally grown inTu''rkiye (Bolu) were determined. The fruit weights of genotypeswere found to be quite variable, ranging from 5.42 g (14MR05) to 12.54g (14MR07). The highest L*, a*,and b* fruit external color values were found tobe 34.65 (14MR04), 10.48 (14MR09), and 9.10 (14MR08), respectively.The highest chroma and hue values were recorded as 12.87 (14MR09)and 49.07 (14MR04), respectively. 14MR03 and 14MR08 genotypes exhibitedthe highest amount of soluble solid content and titratable acidity(TA) as 20.58 and 1.55%, respectively. The pH value was found to bein the range of 3.98 (14MR010)-4.32 (14MR04). Chlorogenic acid(14MR10, 48.49 mg/100 g), ferulic acid (14MR10, 36.93 mg/100 g), andrutin (14MR05, 36.95 mg/100 g) were predominant phenolic acids observedin the fruits of service tree genotypes. The predominant organic acidin all fruit samples was malic acid (14MR07, 34.14 g/kg fresh weightbasis), and the highest quantity of vitamin C was detected at 95.83mg/100 g in genotype 14MR02. Principal component analyses (%) wereperformed to determine the correlation between the morphological-physicochemical(60.6%) and biochemical characteristics of genotypes (phenolic compounds:54.3%; organic acids and vitamin C: 79.9%). It was determined thatmeasured genotypes were important genetic resources in terms of nutritionalvalue.
