title: [Repeatability and heredity in assessing the genotype of breeding bulls].
abstract: Phenotypic correlations between the breeding value of bulls and the level of lactation of their mothers as well as the results of the assessment of their fathers were calculated on the basis of the data of tests and assessments of 1687 diary bulls for quality of their progeny. A relatively weak correlation was detected for the paternal side of the pedigree. This was due to a low efficiency of genotype assessments. A functional relationship between the repetition value and the number of daughters and the number of herds, in which they were used, was determined.
