Породы и типы лошадей: классификация и определения.

The following list of horse and pony breeds includes standardized breeds, some strains within breeds that are considered distinct populations, types of horses with common characteristics that are not necessarily standardized breeds but are sometimes described as such, and terms that describe groupings of several breeds with similar characteristics. While there is no scientifically accepted definition of the term "breed", a breed is generally defined as having distinct true breeding characteristics over a number of generations. Its members may be called purebred. In most cases, bloodlines of horse breeds are recorded with a breed registry. The concept is somewhat flexible in horses, as open stud books are created for recording pedigrees of horse breeds that are not yet fully true breeding. Registries are considered the authority as to whether a given breed is listed as a "horse" or a "pony". There are also a number of "color breed", sport horse, and gaited horse registries for horses with various phenotypes or other traits, which admit any animal fitting a given set of physical characteristics, even if there the trait is not a true breeding characteristic. Other recording entities or specialty organizations may recognize horses from multiple breeds, thus, for the purposes of this article, such animals are classified as a "breed" rather than a "type”.

In some cultures and for some competition sanctioning organizations, a horse that normally matures less than about 145 cm or when fully grown may be classified as a "pony". However, unless the principal breed registry or breed standard describes the breed as a pony, it is listed in this section, even if some or all representatives are small or have some pony characteristics. Ponies are listed in the section below.

If a breed is described as a "pony" by the breed standard or principal breed registry, it is listed in this section, even if some individuals have horse characteristics. All other breeds are listed in the section above. (Because of this designation by the preference of a given breed registry, most miniature horse breeds are listed as "horses", not ponies.)

The distinction is hotly debated between a standardized breed, a developing breed with an open studbook, a registry of recognized crossbred horses, and a designer crossbred. For the purposes of this list, certain groups of horses that have an organization or registry that records individual animals for breeding purposes, at least in some nations, but does not clearly fall to either the breed or type categories are listed here. This list does not include organizations that record horses strictly for competition purposes.

A "type" of horse is not a breed but is used here to categorize groups of horses or horse breeds that are similar in appearance (phenotype) or use. A type usually has no breed registry, and often encompasses several breeds. However, in some nations, particularly in Europe, there is a recording method or means of studbook selection for certain types to allow them to be licensed for breeding. Horses of a given type may be registered as one of several different recognized breeds, or a grouping may include horses that are of no particular pedigree but meet a certain standard of appearance or use.

This section does not include any species within evolution of the horse prior to modern Equus ferus caballus.
