A procedure for chromosome banding in triticale has been shown to be equally effective on maize, Zea mays L., root tip chromosomes. Stocks of known knob constitution were used to demonstrate that differentially stained regions of C-banded mitotic chromosomes corresponded with knobs. The large knob and prominent chromomeres of abnormal chromosome 10 were also differentiated, as was the centric heterochromatin of B chromosomes. However, the large distal heterochromatic portion of the B was not differentiated by the procedure.
