  • For each trait, the chromosome (with S and L indicating short and long arms) and the nearest marker to the LOD peak are listed for all statistically significant QTL. The additive effect of each QTL is shown as a trait unit contribution toward the more maize-like phenotype. The allele contributing to the more maize-like phenotype is indicated by m for ssp. mexicana and p for ssp. parviglumis. The percentage of the PVE by each QTL is given.

  • a Doebley and Stec (1993) dissected the inheritance of all seven of these traits in two distinct maize-teosinte F2 populations, C × M and R × P (see text). This column lists the previous studies that contained a QTL peak for a trait near a QTL peak for the same trait detected in the current study.
