Neighbor-joining phylogenetic tree of maize and teosinte lines rooted with one nicaraguensis accession. A The genetic relationship of all maize plus teosinte. The parviglumis accessions from the Central Balsas race (Par_B) were closest to maize although four mexicana accessions from three races (Mex_H, Mex_P, Mex_C) were mixed among Par_B. B The genetic relationship of all teosinte accessions and all races in parviglumis and mexicana. All materials are marked according to the inferred clusters from the ADMIXTURE analysis. Trop, tropical maize; Temp, temperate maize; Mix, maize lines with membership probabilities in both tropical and temperate groups of < 0.70; Nic, nicaraguensis; Lux, luxurians; Dip, diploperennis; Per, perennis; Hue, huehuetenangsis; Mex, mexicana; Par, parviglumis. The parviglumis races: Par_S, Southern Guerrero; Par_E, Eastern Balsas; Par_O, Oaxaca; Par_B, Central Balsas; Par_J, Jalisco. The mexicana races: Mex_P, Puebla; Mex_C, Central Plateau; Mex_D, Durango; Mex_H, Chalco; Mex_N, Nobogame
