Summary

Equine breeding selection has been developed by applying quantitative genetic methods for calculating the heritability of the complex traits such as performance in racing or sport competitions. With the great development of biotechnologies, equine molecular genetics has come of age. The recent sequencing of the equine genome by an international consortium was a major advance that will impact equine genomics in the near future. With the rapid progress in equine genetics, new applications in early performance evaluation and the detection of disease markers become available. Many new biomolecular tools will change management of horse selection, disease diagnosis and treatment. The purpose of this review is to present new developments in equine genetics and genomics for performance evaluation and health markers after a short summary of the previous knowledge about the genetic components of the exercise performance traits.
