The aim of this thesis was to analyze the polymorphism in position -371bp (related to ATG start codone) of MSTN gene, SNP in position 1984bp of MYF5 gene and influence of these polymorphisms on tenderness, water holding capacity, pH and color of meat. Samples (241) of bull meat of Czech pied cattle were used for analysis. PCR-RFLP method was applied to genotype MSTN and MYF5 genes. For polymorphisms detection was used restriction endonucleases DraI (for MSTN gene) and TaqI (for MYF5 gene). From established genotypes were computed their frequencies and alleles frequencies. The frequencies of genotypes in MSTN gene were AA=0,729, AB=0,258, BB=0,013 and alleles frequencies were A=0,858, B=0,142. The frequencies of genotypes in MYF5 gene were AA=0,181, AB=0,542, BB=0,278 and alleles frequencies were A=0,452 a B=0,548. Using statistical analysis, the influence of genotypes of MYF5 gene on the water holding capacity, pH and the color of meat was determined.
