Abstract
High variability in the natural population of the cornelian cherry in the region of Serbia is an important genetic potential for use in breeding programs. In the course of a 2-year study, significant differences have been noted in morphometric characteristics (fruit weight and flesh to stone ratio were 2.11 to 6.71 g and 78.52% to 88.74%, respectively) and chemical composition of the mesocarp [content of total dry matter (TSC), soluble solid content (SSC), total acids, total and reducing sugars, sucrose, Ca-pectates, vitamin C, proteins, cellulose, anthocyanins, and tannins was recorded 18.26% to 33.39%, 17.40% to 32.37%, 1.62% to 3.75%, 11.77% to 26.30%, 9.50% to 24.07%, 0.38% to 3.25%, 0.32% to 2.44%, 14.56 to 39.22 mg/100 g fruit, 0.20% to 2.71%, 0.43% to 0.95%, 35.63 to 126.53 mg/100 g fruit, and 0.56% to 1.47%, respectively] of 18 cornelian cherry genotypes from Vojvodina Province. The data were compared and analyzed by multivariate techniques [correlation matrix calculation and principal component analysis (PCA)]. The highest positive correlation was found between TSC–SSC and total sugar–reducing sugar (r > 0.95). Using PCA, different genotypes of cornelian cherry can be grouped in clusters based on similarity in their chemical composition.
