The proposal involves mapping QTL affecting milk production and associated traits by selective DNA pooling, in Simmental (dual-purpose); two Holstein anode (multicountry) Brown Swiss (dairy) cattle populations; and in a unique Simmental population produced by crossing a single F1 male (Red Holstein x Simmental) to Simmental as recurrent parent. High-resolution mapping will be carried out for some of the identified QTL, using selective recombinant genotyping within, and identical by descent mapping across the various populations. Allele frequency of QTL alleles, and marker heliotypes associated with positive and negative QTL alleles of active sires will be determined. Theoretical studies needed for use of QTL information for marker-assisted selection (MAS) will be carried out. The end product will be a body of QTL map information and sire marker/QTL information, and of validated methodologies for MAS for milk production traits in dairy and dual-purpose cattle.
