Fig. 3. Alignment of the original mapping populations for the target regions on chromosomes 4(4H), 5(1H), and 7(5H), showing the markers used for genotyping the barley stripe rust resistance QTL pyramid population. "C/B" refers to Calicuchima/Bowman, "S/G" refers to Shyri/Galena. Markers indicated with larger font in the original maps were included to facilitate map alignment. Bmy1 and HvAmyB are different PCR-based markers derived from ß amylase-1 allele sequences.
