Accuracy of estimated breeding values generated in G2 for the candidate population; standard errors of means of 100 replicates were less than 0.006; MatPat: the test sibs inherited maternal and paternal double haploid genomes in G2; Pat: all test sibs inherited paternal double haploid genomes in G2; Mat: all test sibs inherited maternal double haploid genomes in G2; MaxC: the test population was obtained by maximum coancestry mating; MinC: the test population was obtained by minimum coancestry; RAND: the candidate and test populations were obtained by random mating; in each scheme there were 1500 males and 1500 female candidate sibs, 50 sires and 50 dams were selected each generation and heritability was 0.05, 0.1 or 0.4.
