Principal component analysis of the 145 Stevia rebaudiana genotypes for steviol glycosides proportions. Analysis was based on 9 SGs. Graph of variable (left) shows steviol proportion (PST), RebA proportion (PRebA), sweet SG proportion (Psweet; sum of RebM, RebD and RebBF) and bitter SG proportion (Pbitter; sum of RebC, DulA, Rub and SB). Graph of individuals (right) shows the distribution along dimension 1 which explains 95.28% of the variance. The names of the genotypes present at the ends (surrounded in blue) are indicated. The 3 clusters cannot be distinguished (in blue).
