Score plot (A) and loading plot (B) of the principal component analysis (PCA) for 12 phytochemicals [five anthocyanin pigments (Cy3XG, Cy3XGG, Cy3XSGG, Cy3XFGG, and Cy3XCGG), total acylated anthocyanins (TAA), total non-acylated anthocyanins (TNAA), total anthocyanin content by HPLC (TA HPLC), total anthocyanins by spectrophotometry (TA), total phenolics (TPC), β-carotene, and lutein] and antioxidant capacity estimated by four analytical methods (ABTS, FRAP, DPPH, and ORAC), for 29 carrot accessions. Data from years 2018 and 2019 were combined. The numbers of the accessions in the score plot refer to the carrot materials described in Table 1, indicating with black, violet, and orange circles accessions with high (>1000 mg kg⁻¹ fw), intermediate (80–1000 mg kg⁻¹ fw), and low anthocyanin content (<80 mg kg⁻¹ fw), respectively. In the loading plot, the lines starting from the center point of the bi-plot depict the positive or negative association of the parameters with the two principal components.
