  abstract = {{B}ecause of the economic importance of maize and its scientific importance as a model system for studies of domestication, its evolutionary history is of general interest. {W}e analyzed the {P}opulation genetic structure of maize races by genotyping 964 individual plants, representing almost the entire set of similar to 350 races native to the {A}mericas, with 96 microsatellites. {U}sing {B}ayesian clustering, we detected four main clusters consisting of highland {M}exican, northern {U}nited {S}tates ({US}), tropical lowland, and {A}ndean races. {P}hylogenetic analysis indicated that the southwestern {US} was an intermediary stepping stone between {M}exico and the northern {US}. {F}urthermore, {S}outheastern {US} races appear to be of mixed northern flint and tropical lowland ancestry, while lowland middle {S}outh {A}merican races are of mixed {A}ndean and tropical lowland ancestry. {S}everal cases of post-{C}olumbian movement of races were detected, most notably from the {US} to {S}outh {A}merica. {O}f the four main {C}lusters, the highest genetic diversity occurs in highland {M}exican races, while diversity is lowest in the {A}ndes and northern {US}. {I}solation by distance appears to be the main factor underlying the historical diversification of maize. {W}e identify highland {M}exico and the {A}ndes as potential sources of genetic diversity underrepresented among elite lines used in maize breeding programs.},
