Mean of five replicated simulations, except for BayesA which is based on one replicate. LS, least squares; BLUP, best linear unbiased prediction; BayesA, Bayesian method with inverse chi-square prior distribution; BayesB, Bayesian method where the prior density of having zero QTL effects was increased; rTBV;EBV, correlation between estimated and true breeding values (equals accuracy of selection); bTBV;EBV, regression of true on estimated breeding value.
