  • a Markers that flank the 1 − LOD confidence interval.

  • b The position that defines the 1 − LOD confidence interval around the position of peak likelihood for the QTL.

  • c The genome location of each genetic marker was obtained through the integration of the IBM linkage map (http://www.maizegdb.org/qtl-data.php) and the maize B73 genome sequence (Maize Genome AGP version 1, release 4a53; www.maizesequence.org).

  • d The three cis-QTL are shown in boldface.

  • e Total r2 was obtained by fitting all the significant QTL in the model simultaneously.
