  1. Standard errors are given in parantheses.
  2. 1 CONV = conventional breeding strategy without genotyping.
  3. 2 W-FAM = genomic selection with marker effects estimated within full-sib families and combined with conventional BLUP family breeding values when 100% of the candidates were pre-selected.
  4. 3 GS_POP = genomic selection with marker effects estimated population wide and no pre-selection.
  5. 4 A trait measured on the selection candidates themselves.
  6. 5 A trait measured on full-sibs of the selection candidates.
