However, fruit located in the most mature main cluster (right side of the PCA plot, Fig. 1A), mostly displaying maximum yellowness (Table 2) and alltrans--carotene contents (Table 3), differed from the other main cluster rather in PC2 than in PC1. Rightmost position on the PC1 axis(Fig. 1A) primarily resulted either from minimum TA (N2B, N5B/C; Table 4) or minimum chlorophyll b contents (N4C; Table 3), always combined with maximum TSS ≥ 10.5 g hg−1 (Table 4) and maximal b∗m ≥ 32.6 (Table 2).
