Table 2 Average true breeding value (TBV) of the top 10% candidates based on genomic breeding values predicted by different reference populations (PB: purebreds in GP2; CB_extreme: two_tailed crossbreds in DLY; CB_random: random crossbreds in DLY) with different population sizes (500, 1000, 2000, 3000, 4000, 5000, 6000, 6500) and two methods (GBLUP and BSLMM) for different heritabilities (\({{h}}^{2}\))
