Principal component analysis (PCA) of traits based on best linear unbiased estimates (BLUPS). Abbreviations: Number of lateral roots in the first segment (NoLat 1st) or second segment (NoLat 2nd), length of representative lateral root in the first segment (MedLat 1st) or second segment (MedLat 2nd), maximal lateral root length in the first segment (MaxLat 1st) or in the second segment (MaxLat 2nd), total number of lateral roots (NoLatTot), elongation rate crown roots (ERCr), length of crown roots at solution change (intercept; ICCr), embryonic root dry weight (DWER), crown root dry weight (DWCR), leaf greenness (SPAD), leaf area measured (LAm), dry weight shoot (DWS), leaf area pixel based (LAPix), shoot pixel count at solution change intercept (ICS), shoot pixel count development (ERS), N content in the leaf in % of total dry weight (N). The numbers in the PCA plot correspond to the EU_IDs. For the corresponding genotypes see “Cultivation in the RADIX platform” in the “Methods” section
