The Old Kladrub horse is the only Czech horse breed with breeding continuity in the Czech Lands for several hundreds of years. All individuals are related to each other due to the small size of the population, so breeding should be organized in order to minimize an increase in their genetic relationship. Hence the population should be divided into units with the least genetic relationship possible. Relationships between individual animals can be interpreted as correlation coefficients. Individual animals can be included in classes on the basis of their relationships. Horse inclusion in the classes was mostly in agreement (particularly for the method of centroid components) with the present taxonomic classification according to genealogical lines, up to groups of progenies after the separate sires. Genetic relationship between white horses and black horses is low, which documents that each color type has been bred autonomously in the history. Genetic relationship between the individuals and within the classes and between the color types makes it possible to organize breeding without foreign gene immigration
