Principal-component analysis (PCA) of 46 cultivars of common buckwheat based on GBS data mapped on all genome scaffolds. Graph of the first two axes (x-axis for PC1 and y-axis for PC2) from PCA. The proportion of variance explained by each component is given in parentheses along each axis. Red and blue represent short- and long-styled plants, respectively
