Five microsatellite loci (ILSTS093, BM143, ILSTS097, MB062, BM2320) located on bovine chromosome 6 were tested as potential markers for milk production traits in five families of the Czech Pied breed. The effect of segregating marker alleles was estimated in 33 sons of 5 grandsires using a granddaughter design. Significant associations between markers within grandsire and breeding values for milk protein and fat yields were detected for four loci (ILSTS093, BM143, MB062, BM2320). None of the selected markers showed a significant influence on the breeding value for milk yield. Two new alleles were detected at microsatellite locus MB062 (162 and 164 bp) and one new allele was identified at microsatellite locus BM143 (85 bp).
