Figure 2From: Exploring molecular backgrounds of quality traits in rice by predictive models based on high-coverage metabolomicsGenetic subtypes in 3 spaces. (a) Principal coordinates analysis of the genetic distances between the varieties indicate the presence of 3 major sub-populations, Indica I (20 varieties), Indica II (34 varieties) and Japonica (16 varieties). (b) PCA of the 17 quantitative traits; (c) PCA of the complete summarized metabolite profile dataset with a total of 1652 peaks. Percentages indicate the ratio of explained to total variance.Back to article page
