Abstract
SUMMARYThe C-banded karyotypes of several maize stocks, including one with knobs in almost all positions known in maize chromosomes, are presented together with the evidence that large C-bands or knobs alter the relative arm length of the chromosomes involved. All the aspects of the differential Giemsa staining are discussed, including the centromeric heterochromatin, Nucleolar Organizing Region (NOR) heterochromatin, the satellite of chromosome 6, as well as the heterochromatic segments of the B-chromosomes observed both in mitotic metaphase and at the pachytene stage of meiosis.
