Clear G‐banding patterns have been obtained in the chromosomes of Hordeum vulgare , Aegilops squarrosa, Oryza sativa, Sorghum vulgare, Setaria italica , and Zea mays by combining an improved slide preparation technique and the ASG (Acetic acid/Saline/Giemsa) method. All species examined show multiple, closely adjacent bands all along their G‐banded chromosomes. G‐banding patterns identified homologous and differentiated nonhomologous chromosomes. In G‐banding patterns, barley and Ae. squarrosa are more similar, but they are more different from rice, sorghum, millet, and maize, which are more similar. Q‐banding was performed in Zea mays with quinacrine mustard. Except for very few bands, Q‐banding patterns corresponded to G‐banding patterns. The similarities of G‐banding patterns in plants and mammals, consistency of relationships among experimental species as demonstrated by both G‐banding of chromosomes and classic systematization, and the techniques of G‐banding in plants are discussed.
