The low nutritive value of maize endosperm protein is genetically corrected in quality protein maize (QPM), which contains the opaque2 gene along with numerous modifiers for kernel hardness. We report here a two generation marker-based backcross breeding program for incorporation of the opaque2 gene along with phenotypic selection for kernel modification in the background of an early maturing normal maize inbred line, V25. Using the flanking marker distances from opaque2 gene in the cross V25… CONTINUE READING
