Reliable breed assignment can be performed with SNPs. Currently high density SNP-chips are available with large numbers of SNPs from which the most informative SNPs can be selected for breed assignment. Several methods have been published to select the most informative SNPs to distinguish between breeds. Here we evaluated Delta, Wright's FST and Weir and Cockerham's FST and extended these methods by adding a rule to avoid selection of sets of SNPs in high LD providing the same information; SNPs that had a r(2) value > 0.3 with any of the SNPs already selected were discarded. The different selection methods were evaluated both for the 50K SNP and the 777K Bovine BeadChip. Animals from four cattle breeds (989 Holstein Friesian, 97 Groningen White headed, 137 Meuse-Rhine-Yssel and 64 Dutch Friesian) were genotyped. After editing 30,447 and 452,525 SNPs were available for the 50K and 777K SNP chip, respectively. All selection methods showed that only a small set of SNPs is needed to differentiate among the four Dutch cattle breeds, while comparison of the selection methods showed small differences only. In general the 777K performed marginally better than the 50K BeadChip, especially at higher confidence thresholds. The rule to avoid selection of SNPs in high LD reduced the required number of SNPs to achieve correct breed assignment. The Global W&C FST performed marginally better than other selection methods. There was little overlap in the SNPs selected from the two BeadChips, while the number of SNPs selected was about the same.
