Fig. 1. Bread wheat genotypes assayed with SSR locus Xpsp2999 = locus Glu-A3 (1AS) and Xpsp3000 = Gli-B1 (1BS). Xpsp2999 amplified a single major band and Xpsp3000 two (see arrows). Each main band has "stutter" fainter bands separated by 3 bp produced by errors of the polymerase during the amplification of these trinucleotide SSRs. The size of the main bands in base pairs is detailed at the bottom of the figure.
