Fig. 2. A chromosome 6B RFLP linkage map from the cross of LDN(DIC-6B)/Vic and Renville. This map has a total map distance of 94 cM, and the largest gap was 13.2 cM. Centromere location is indicated by black rectangle labeled C. Short arm is on top

Fig. 5. Graphical genotyping of eleven recombinant inbred (RI) lines with recombinations near the grain protein concentration locus chromosomal region. Recombination breakpoint was from raw mapping data for each RFLP locus, and marker orders and map distances were from the chromosome 6B map. Grain protein concentration of RI lines was from the 1996 data combined over three locations. Only RI lines with chromosome breakage (recombination) near the protein locus region are shown
