Fig. 2 Amplified fragment length polymorphism (AFLP) chromatogram showing runs of Jodon and Kaybonnet DNA using two independent DNA preparations run on different days using Mse + CAA and EcoRI + AAG primers. Chromatograms 1 and 3 = Jodon, Chromatograms 2 and 4 = Kaybonnet. Arrows indicate polymorphic peaks as follows: peaks that are polymorphic between the two cultivars consistently between duplicates (a); a peak that appears to be polymorphic between Jodon and Kaybonnet for Chromatograms 1 and 2, but the polymorphic peak is not present in the duplicate Jodon run on Chromatogram 3 (b); peaks of variable heights between the duplicate runs for Jodon (Chromatograms 1 and 3) (c)
