(A) Diagrams showing pedigree of three independently formed allohexaploid wheat lines, designated as Allo-960, Allo-AT5, and Allo-AT9, each with three to five selfed generations available for this study. (B) Typical chromosomal constitutions for the selected individuals from each of the three allohexaploid wheat lines, as revealed by multicolor GISH. All plant individuals used for this study are with transgenerational chromosomal stability at the subgenomic level (euploidy and lack of any intergenomic rearrangements), as shown in B, which is highly similar to the natural common wheat, T. aestivum. The pink-, green-, and blue-colored chromosomes are of the BB, AA, and DD genomes, respectively.
