Fig 1. Generalized idiogram of wheat A and B genome chromosomes.

A and B—wheat genomes; 1–7—homoeologous groups; S and L—short and long arm of a chromosome, respectively. Large permanent C-bands are shown as solid blocks; polymorphic C-bands are shown as shaded blocks; small inconsistent C-bands are indicated by dashed lines. Positions of C-bands are numbered at the right-hand side of each chromosome. The 112 C-bands considered in “chromosomal passports” are shown in red; 38 C-bands most essential for discrimination of karyotypic groups are indicated with *.
