Heterochromatic banding patterns in Allium

II. Heterochromatin variation in species of the paniculatum group
  • Canio G. Vosa


The karyotypes of nine Allium species of the paniculatum group have been analysed with fluorochromes and C-banding techniques. All the species possess reduced as well as enhanced fluorescence bands which are also differentiated by C-banding and which correspond to constitutive heterochromatin. Heterochromatic segments are located in distal and intercalary positions leaving sizeable procentric regions devoid of bands. These features are indicative of a close relationship between the species of this group. However, the proportion of heterochromatin as a percentage of total chromosome length varies from about 30% to 10–15%.
