Principal Component Analysis (PCA) scatter plots of different berry-related traits, including total soluble solids (TSS), acidity (Acid), TSS/Acid ratio (T/A), pH, total anthocyanin content (TAC), luminosity index (L*), hue angle (h°), and chroma index (C*). Other previously characterized traits for the same muscadine population, including total phenolic content (TPC), total flavonoid content (TFC), and DPPH antioxidant activity, were added to the analysis. The scatter was generated using the average of three biological and three technical replicates, among three years (n = 27). According to the PCA model, 31.08% and 21.19% of the variance were explained by the PC1 and the PC2 principal components, respectively.
