AQPS ("Autre Que Pur-Sang"), translated as "Other than thoroughbred", is a general term used in France to refer to horses not listed as Thoroughbreds. Anglo-Arabians, Selle Français (or French Riding Horse), and French Trotters plus all other crossbreds can be qualified as AQPS. For racing purposes, each breed has its own studbook. The designation usually means one parent is not listed in the Thoroughbred stud book and almost always applies to those horses with Selle Francais breeding in the dam line.
The AQPS racing breed developed around the end of the 19th century when French farmers began to cross cart horse mares with Thoroughbred stallions to produce a fast and hardy horse that has proven to be best suited for steeplechase racing. The average person most likely would not be able to see any difference between an AQPS and a Thoroughbred as evolution of the breed has resulted in AQPS horses today averaging 80 percent Thoroughbred and 20 percent French saddle-bred.
The Association des Eleveurs d'AQPS is a member partner in the French Racing and Breeding Committee (FRBC).
Probably the best-known AQPS horse in the world is Al Capone II, who won the Group One Grand Steeple-Chase de Paris in 1997 plus seven consecutive Group One Prix La Haye Jousselin steeplechase races at Auteuil Hippodrome from 1993 through 1999. His full brother The Fellow won the Prix La Haye Jousselin in 1990, the Grand Steeple-Chase de Paris in 1991 and enjoyed even greater success in England where he won the King George VI Chase in 1991 and 1992 and the Cheltenham Gold Cup in 1994.
Mon Mome, winner of The Grand National in 2009, is an AQPS horse.
