Azteca
Registry Code: AZT
Also Known As: American Azteca
Originating from Mexico, the Azteca is a breed created by crossing Iberian (PRE/Andalusian/Lusitano) or Mexican Criollo horses with the American Quarter Horse. When the breed reached the USA, American Paint Horse bloodlines were introduced, adding the possibility for various white patterns.
Ideal Height: 14.3 – 15.1 hh (150 – 155 cm)
Acceptable Height Range: 14.3 – 16.1 hh (150 – 165 cm)
Most Common Colours: Grey, followed by all other solid colours excluding champagne dilutions
White patterns are acceptable in American Aztecas (those carrying American Paint Horse lines)
Note that an Azteca should maintain 25% QH, Criollo and/or Paint bloodlines at all times. Ideally Aztecas are 75% Iberian, though as little as 37.5% Iberian blood in Azteca A classified horses will be recognized by the IHA. Azteca A horses that are more than 75% Iberian resulting from an Azteca x Aztea cross are considered Azteca. Azteca A horses that are more than 75% Iberian resulting from an Azteca x Iberian cross may alternatively be registered as "Iberian Halfbred."
If a Mexican Azteca and an American Azteca are crossed, the resulting foal must be classified as an American Azteca if it has inherited a white pattern, but may be classified as either American or Mexican if is it solid coloured. In the case of American x Mexican Azteca foals, Azteca A x any = Azteca A, and all other crosses should be classified according to the best match on the appropriate (Mexican or American) chart.
