Abstract: 
In this study the genetic relationship between six separate populations (Silesia n = 406; Saxony n = 48; Thuringia n = 38; East Friesian n = 50; Denmark n = 42; The Netherlands n = 19) of the old type of Oldenburger and Ostfriesen were investigated, In addition, comparative analyses were made to three German riding-horse populations (Hanover n = 227; Oldenburg n = 86; Hessian n = 68). A total of fifteen genetiv polymorphic markers (eight protein and enzyme loci, seven blood groups) in all 68 alleles were investigated. Based on the estimated allele frequencies the populations were further characterized for their genetic variability on the basis of heterozygosity (H-exp), number of alleles (n(a)), effective number of alleles and the genetic distances (D-A) between the populations were estimated. The degrees of heterozygosity were as follows: Silesia 0.401; Saxony 0.418; Thuringia 0.435; East Friesian 0.427; Denmark 0.406; The Netherlands 0.350, and, for the three German riding-horse populations, Hanover 0.397; Oldenburg 0.404 and Hessian 0.407. The East Friesian population had the highest number of effective alleles n(e) = 33.58 and the Netherlands population the lowest number of effective alleles n(e) = 28.61. The values for the German riding-horse populations all lay just below 32. The closest genetic relationship was found between the populations of Silesia and Saxony D-A = 0.015 and the greatest distance between the populations of Thuringia and the Netherlands D-A = 0.055. The population in the Netherlands displayed the greatest genetic distances from the further investigated populations. The East Friesian population exhibited the lowest genetic distance to the German riding-horse populations, in particular the Oldenburg population.
