Fig. 5From: Quantitative trait loci analysis of glucosinolate, sugar, and organic acid concentrations in Eruca vesicaria subsp. sativaPrincipal Component Analysis biplot representing 52.64% of metabolite variance across the Eruca vesicaria subsp. sativa mapping populations grown in Italy and the UK. PC1 and PC2 explain 39.9 and 13.25% of the total variation between samples, respectively. Eigenvalues for PC1 and PC2 were 7.88 and 2.65, respectively.
