Fig. 1. Visualization of C genome chromosomes in BC₁ plants by GISH. A: Plant BC₁-855 whose paternal parent was jointed goatgrass showed 12 C genome chromosomes. B: Plant BC₁-932 whose paternal parent was wheat showed six C genome chromosomes. C: Plant BC₁-934 whose paternal parent was wheat and most likely resulted from meiotic chromosome restitution showed seven C genome chromosomes.
