^aPedigree-based model (PED) fit BCWD records from 2005 families.

^bThe validation fish or potential breeders were mated to generate 31 progeny testing full-sib families.

^cThe single-step GBLUP (ssGBLUP) and weighted ssGBLUP (wssGBLUP) methods used in training models analysis all fish that had genotype and phenotype records and had any type of pedigree relationship (parents, full-sibs, half-sibs, etc.).

^dThe Bayesian methods BayesB and BayesC used in training model analysis only those fish that had matched genotype and phenotype records without missing data.

^eNa indicates either non-available or non-needed data cell.

^fProgeny tested breeders are fish from 2005 families that were used as breeders to generate 2007 families.
