  1. Our STRUCTURE analysis detected four groups, or populations, which we have named Central (group 1, yellow in Fig. 1), South (group 2, orange in Fig. 1), AR/MS (group 3, Arkansas/Mississippi, pink), and Texas (TX, group 4, blue). We give the percent membership of each accession to each STRUCTURE group to show the extent of admixture
