The predominant coat colors in Vyatka horse breed are bay-brown (69.6 %) and mousey (20.8 %). Among the genotyped livestock, three genotypes of the base bay coat color (EE/AA, EE/Aa, Ee/AA) and two genotypes of the base solid blackcock (EE/a/a, Ee/aa) have been detected. The proportion of horses with Cr allele is 2.1 %. In Vyatka horse breed, three isabelline-brown horses (Cr/Cr) have been recorded and the presence of W20n allele was detected. Among the horses genotyped, 35.5 % are DD homozygous, 61.3 % are heterozygous (Dd1, Dd2), 3.2 % have the nd2/nd2 genotype. Allele d2 against the background of D does not always cause the presence of “wild” markings, unlike D/D. The influence of Dun-factor on the depigmentation area has not been detected. 39.9 % of horses have white markings (including 30 % of stallions), which are mainly facial markings (59.8 %), less often they are leg markings (21.6 %) or both facial and leg markings (18, 6 %).
