Abstract

In German Holstein population a very signifi cant QTL with effects on milk yield trait (MY) was mapped on chromosome 6 and 20 to the interval BM143–ILSTS97 and AGLA29–ILSTS72, respectively. Where, three markers BM143, FBN13 and ILSTS97 on chromosome 6 and two markers AGLA29 and ILSTS72 on chromosome 20 were associated with highly signifi cant effects (P<0.01) for milk yield. Findings from this study could be used in subsequent fine-mapping work and applied to marker-assisted selection (MAS) of dairy production traits.
