Extended Data Fig. 8: Wild einkorn γ race introgression into domesticated einkorn.

a, Geographical projection of the second PCA axis based on variants found only in the large introgressed segment on chromosomes 5A. b, Geographical projection of the first PCA axis based on variants found only in the large introgressed segment on chromosomes 7A. Blue colour indicates γ accessions with close genetic relatedness to the introgressed segments found in domesticated einkorn accessions. Black dots represent the coordinates of γ accessions. The analysis was done excluding α and β accessions. Maps in both a and b were created using the Kriging function in the fields v10.3 R package (https://cran.r-project.org/web/packages/fields). c, The proportion of γ race introgression in domesticated einkorn. Each dot represents the coordinates of a domesticated einkorn accessions. Dark blue and light green represent the highest and the lowest proportions of γ introgressions in domesticated einkorn, respectively (legend at top right). The map was created using the graphic plot function in R.
