^a QTL codes are given for the trait ND only (see text).
^b Position of the QTLs based on the Gaspé Flint introgressions position and length, as estimated on the reference maize map "Genetics 2008" http://www.maizegdb.org/map.php.
^c Markers or marker-intervals delimiting the Gaspé Flint introgressions at the QTL chromosome regions.
^d QTL genetic effects computed as (ILLs - B73)/2, where ILLs is the trait mean value of all IL lines sharing the same introgression at the QTL region.
