Sorghum DTF QTL indicated as green segments on sorghum chromosome. Projected locations of the mid-point of the sorghum DTF QTL onto the syntenic maize chromosomes detailed. Locations of the maize DA (blue) and DS (red) significant markers indicated. Co-ordinates of segments of maize chromosomes detailed (based on maize NAM map) and orientation of maize chromosomes, relative to sorghum chromosome, indicated by arrows. Asterisks indicate maize QTL with mid-points less then 10cM from the location of the sorghum QTL mid-point. * * * * * * * * ** * * * SBI-01
