Abstract
Principal components analysis of 46 chromosome knob positions and B chromosomes for 61 accessions of annual teosinte (in 12 groups) and 207 accessions of maize (in 87 groups) produced results which did not entirely agree with previous groupings. Teosintes of northwest and southeast Guatemala (races Huehuetenango and Guatemala) were widely separated from maize and from all other teosintes; however, teosintes of east Mexico-Distrito Federal (race Chalco) were also widely separated from maize and other teosintes. Teosintes of south Chihuahua (race Nobogame) grouped separately from other teosintes, suggesting that race Nobogame is not simply a northern extreme of race Central Plateau. Teosintes of east Michoacan and west Mexico (recently grouped into the Balsas race) grouped together but separately from other teosintes. The latter teosintes may merit special designation in a racial taxonomic system. Only the Central Plateau teosintes consistently overlapped with maize OTU's for the first few principal components. Even in that case there was no consistent association between the Central Plateau teosintes and any specific race of maize.
