Precision of genetic parameters and breeding values estimated in marker assisted BLUP genetic evaluation

Table 5 Accuracies of estimated breeding values in MA-BLUP evaluation models that were only based on daughter yield deviations (DYD) for bulls or on DYD for bulls and yield deviations for cows

Phenotypic information	Pedigree depth	Missing genotypes	Proven bulls	Cows	Young bull candidates
			MA-BLUP	MA-BLUP	MA-BLUP	Residual polygenic	QTL-EBV
DYD	short	none	0.942	0.388	0.480	0.437	0.296
DYD-YD	short	none	0.944	0.679	0.556	0.497	0.348
DYD-YD	deep	none	0.945	0.689	0.566	0.501	0.437
DYD-YD	deep	moderate	0.945	0.689	0.563	0.501	0.418
DYD-YD	Deep	extensive	0.945	0.688	0.560	0.500	0.390

Different pedigree structures (short and deep) and levels of missing genotypes (none, moderate and extensive) were applied; accuracies are shown for the overall breeding values of MA-BLUP evaluations, the residual polygenic breeding value and breeding value for the QTL position (QTL-EBV); in breeding value estimation, the estimated variance components were used; the results are averages over 100 replicates per scenario.
