QTL detected for grain starch content in the two RIL populations under each environment and in combined analysis.

aValues in the brackets were the intervals between QTL and its flanking markers.bBin locations of the flanking markers from Maize GDB (http://www.maizegdb.org).cGenetic map position by cM.dA means additive effects estimated with QTL Cartographer.eR2 means percent of phenotypic variance explained by each QTL.
