“…These values also indicate that the breeds are not differentiated enough and that they may have a common history and breeding practices. The estimated F ST values are lower than those determined between two colour varieties within the Old Kladruber horse breed (F ST = 0.082) (Kasarda et al 2016). These results are fully consistent with the values of average inbreeding coefficients and F ST estimated by Vostra-Vydrova et al (2016) by means of pedigree analysis.…”

“…Estimated parameters of genetic diversity exhibited non-significant differences between breeds (Table 2), which fully corresponds to their historical development. Genetic diversities within the studied breeds reached similar values to those in the Old Kladruber horse (Vostry et al 2011;Kasarda et al 2016), the breed that also belongs to genetic resources of the Czech Republic. The determined values of genetic diversity were lower than e.g., those in Polish cold-blood horses (Iwanczyk et al 2006) or Polish Konik (Szwaczkowski et al 2016).…”

Vostrá-Vydrová H., Vostrý L., Hofmanová B., Moravčíková N., Veselá Z., Vrtková I., Novotná A., Kasarda R. (2018): Genetic diversity and admixture in three native draught horse breeds assessed using microsatellite markers. Czech J. Anim. Sci., 63,[85][86][87][88][89][90][91][92][93] In this study, we aimed to estimate and compare genetic diversity of two native draught horse breeds and check the possible influence of Noriker breed population on these native breeds. Genetic analyses of relationships and admixture were performed in two native endangered draught horse populations (Silesian Noriker and Czech-Moravian Belgian horses) and one open breed (Noriker). Totally 104 alleles from 13 microsatellite loci were detected in 1298 horses. The average number of alleles per locus was the highest in the Czech-Moravian Belgian horse (7.62) and the lowest in the Silesian Noriker (7.31), the differences were non-significant, whereas the observed and expected heterozygosities per breed ranged from 0.680 (Czech-Moravian Belgian) to 0.719 (Noriker) and from 0.678 (Silesian Noriker) to 0.714 (Noriker). The estimates of Wright's F ST between each pair of breeds indicated a low level of genetic segregation. At the individual level across the analyzed population, formation of two clusters was observed with respect to historical breed development. Moreover, the membership probability outputs showed that the frequencies of alleles varied across the two main regions represented by the Czech-Moravian Belgian and other analyzed breeds. Our results indicated high genetic variability, low inbreeding, and low genetic differentiation, especially between Silesian Noriker and Noriker, which is caused by the high level of admixture. This high level of admixture was in accordance with geographical location, history, and breeding practices of the analyzed breeds. The Silesian Noriker and Noriker breeds seem to be the most genetically related and the decision to consider them as the same population is thus highly supported. The study provides data and information utilizable in the management of conservation programs planned to reduce inbreeding and to minimize loss of genetic variability.

“…1). The obtained level of genetic diversity within breeds is comparable to the results found in other warmblood horses, including for example Haflinger (Vostrý et al, 2015) or Old Kladruber horses (Kasarda et al, 2016). The principal component analysis was performed to describe the highest proportion of variance in dataset.…”

The aim of this study was to evaluate the genetic structure and potential loss of diversity within three horse breeds: Lipizzan (42), Furioso (38), and Nonius (18) on molecular-genetic level. The genotyping data were obtained from in total 98 individuals presenting the genepool of analysed breeds in Slovakia. The values of gene diversity (0.72) as well as heterozygosity (0.89) showed the prevalence of heterozygotes within each population. The negative value of F IS index (-0.25) pointed, in particular, to good level of diversity and balanced proportion of homozygous and heterozygous animals in populations, i.e. HWE equilibrium. The Shannon's information index (I=1.41) confirmed sufficient level of variability mainly in order to maintain the current state of biodiversity for future generation. The genetic distances on intra-and inter-population level revealed clearly distribution of individuals into the three separate genetic clusters. The highest genetic similarity was found between Nonius and Furioso breeds (DA=0.16). However, the pairwise F ST values and PCA analysis were not fully sensitive to detect the genetic differences among those breeds. We were able to detect only two genetic clusters, when Furioso and Nonius were linked together. This can be explained mainly by the use of English Thoroughbreds stallions and mares in building up process of both breeds. Considering that the results related to the state of diversity in presented breeds are correct, they can be used as basis for the further progress in breeding programs which is necessary to prevent the loss of heterozygosity and increase of inbreeding.

“…Quite surprising is a fact that genetic differences estimated between draft horse breeds was smaller than between two colour variants of Old Kladruber horse. Genetic diversities within the studied breeds reached similar values to those obtained in the Old Kladruber horse by Kasarda et al (2016). The determined values of genetic diversity were lower than e.g., those in other European endangered population -Polish Konik (Szwaczkowski et al 2016).…”

The aim of the present study was to analyse the genetic diversity of the endangered horse breeds kept in the Czech Republic. A set of 13 microsatellites was used for genotyping 349 Silesian Norikers, 397 Norikers, 552 Czech-Moravian Belgian horses, 271 Old Kladrubers (175 greys, 95 blacks) and 241 Hucul horses. The proportion of obtained heterozygosity indicates no major loss of genetic diversity within analyzed breeds. The Wright's FST and genetic distances indicated genetic segregation of both colour varieties of the Old Kladruber breed and small genetic distances between draft horse breeds. Moreover, the membership probability outputs showed that the frequencies of alleles varied across the three main regions. First region is represented by draft horse breeds, second region is represented by Old Kladruber horse and the last is represented by Hucul breed. The study provides data and information utilizable in the management of conservation programs in order to reduce inbreeding and to minimize loss of genetic variability.
