PCA with 76,102 markers. Samples are colored according to geographic origin, row type, annual growth habit and domestication status. Color codes are defined in the inset map of a and the legends of b–d. The proportion of variance explained by the principal components is indicated in the axis labels of a. The proportion of variance explained by the principal components is indicated in the axis labels. The map was created with the R package mapdata.
