Principal Component Analysis using the 161 walnut accessions and the 14 traits quantified using the X-ray CT method. a PCA correlation circle of the 14 variables (dimensions 1 and 2), b Scree plot of the percentage of variances explained by the first ten dimensions, c PCA scatterplot of the 161 accessions (dimensions 1 and 2), d Correlation plot of the 14 variables (dimensions 1 and 2). For a and c plots, color gradient indicates the quality of the representation of each variable given by the squared cosines cos2
