The aim of the study was evaluate sporting breeds of horses used for show jumping sport in the Czech Republic. In the literary section is describes the show jumping sport, history of show jumping sport and characterization of the breeds which are used in the Czech Republic and worldwide in the show jumping sport. The work insludes statistical evaluation of the effect breed on the performance of the horses. Performance is evaluated by the auxiliary points PPB to one start. Auxiliary points expressed the preformance of the horses. The points are calculeted according to the real resulsts in the competitions in the criminal points. The criminal points are converted to the auxiliary points. Data was used from the Summary of sport horses of 1995, 2005 and 2014, issued by the Czech Equestrian Federation. Data was further processed and statistically analyzed. Statistical conclusiveness of the breed on the performance was confirmed, in some cases it is also highly statistically conclusive. Breeds were further tested to determine which breed is the most performance and the most appropriate for show jumping sport. In the 1995 it was found, that the most performance for show jumping sport of the ranking top 300 horses are germans warmblood breeds with 6,25 PPB. In the 2005 was the most performance breed hanoverian horse with 8,30 PPB. In the 2014, besides germans warmblood breeds with average value of 8,28 PPB come to the foreground other warmblood breeds with 9,44 PPB and breeds like belgian warmblood with 8,07 PPB and holland warmblood with 7,75 PPB. In the statistics of all started horses in the 2014 was the most performance breed belgian warmblood with a value of 8,81 PPB. Statistically conclusiveness effect on performance was found also for sex. When the most performance are stallions with 4,56 PPB, then mares with 3,91 PPB and the geldings with 3,75 PPB are least performance.

The objective of the thesis was to evaluate the effect of foreign sports breeds of horses in the breeding of warm-blooded horses upgraded for jumping performance in the Czech Republic. The source for creating a database were data from show jumping competitions obtained from the Přehledu sportovních koní ČR (Survey of sports horses of the Czech Republic) 2000 -- 2009. The sports performance of the horses is expressed as PPB (average auxiliary points). The data were processed statistically using the GLM linear model in the UNISTAT 5.1 statistical programme. If the effect was statistically significant we used Scheffe's method of comparison to compare the multiple differences in the values. On the basis of statistical evaluations of groups of breeds representing the individuals born in the Czech Republic we discovered that the pedigree group AUTWB4 achieved the highest PPB value (4.52), i.e. 50% blood of the Austrian warm-blooded horse. The most numerous pedigree group in the entire population of the monitored sports horses based on the number of PPB points (14.36%) was the group where no dominant breed prevailed in the pedigree. The most frequently used foreign breed in breeding horses for show jumping performance is the Holstein warm-blooded horse. In evaluations of the performance of horses based on the country of their birth the highest PPB values (4.25) were achieved by individuals born abroad. In terms of the effect of the year of their start the highest PPB value (3.37) was achieved by horses starting in 2009 when also most of the PPB values (10.72%) were recorded. Evaluations of the differences between the sexes showed that stallions achieved the highest PPB values (3.84) and that the most numerous group were mares (47.20%). In terms of the differences in the ages of the horses the highest PPB value (3.43) was achieved in the group of 9-year-old horses and the most numerous group in show jumping competitions based on the number of PPB's (14.91 %) were 6-year-old horses.
