  1. 1Smaller numbers of lines were examined for the labor-intensive stem density and NIR measurements.
  2. 2Bd1-1 was not included in this experiment because of its known long vernalization requirement.
  3. 3Lines BdTR2g and BdTR5i were omitted from the CoMPP analysis, because insufficient material was available.
