The difference in the AQHA Appendix and Quarter Horse registries.
In my previous post, Thoroughbred Recording, I gave you all a little information about listing a Jockey Club-registered Thoroughbred on AQHA records for breeding purposes. But what happens once the foal is born? Since AQHA is a breed registry, how does a horse that is not completely Quarter Horse get registered and differentiated from full-blooded Quarter Horses?
AQHA has created a special registry and numbering system for these Quarter Horse-Thoroughbred crosses. These horses are considered Quarter Horses, but are named for the registry system created for them — Appendix. They are denoted by a registration certificate that is white with a gold border (or completely gold if you have an older-style certificate) instead of blue. Their registration numbers also begin with an X. AQHA has registered more than 600,000 Appendix horses to date.
