The aim of this thesis was to perform association analysis of UASMS1 polymor-phism in leptin gene with parameters of beef quality, studied on a group of Czech Fleckvieh bulls. The group of 236 bulls was genotyped by direct sequencing of the PCR product. Individual genotypes were processed into a database and statistical evaluation of association was performed by using SAS software. The UASMS1 polymorphism had a highly significant effect on palmitoleic acid content (p = 0.00006) and stearic acid content (p = 0.0005) between CT and TT genotypes. There was a significant value in myristoleic acid content (p = 0.0117) between genotypes CT and TT and in linolelaidic acid content between both genotypes CC and CT (p = 0.0340) and CC and TT (p = 0.0417). Values relating to the effect on dry matter content (p = 0.0746) and colour of meat (p = 0.0541) had only approaching evidentiary values. The influence of genotype on intramuscular fat content or other parameters of beef quality has not been demon-strated in this study.
