  1. aThe QTLs detected; the name includes information of seedling cultivation time, trait abbreviation, and chromosome number
  2. bThe additive effect of putative QTLs, with positive values indicating that alleles from Zong3 increased the trait and negative values indicating that alleles from Yu87–1 increased the trait
  3. cThe percentage of phenotypic variation each putative QTL
  4. dThe bin positions of the QTLs, based on the B73 physical map from the website (http://www.maizegdb.org)
