Abstract
THE cultivated cottons (Gossypium barbadense and G. hirsutum) are allotetraploids derived from two geographically isolated diploid species ; one, an Asiatic species, donating the A genome and the other, an American species, donating the D genome. The chromosomes of the diploid progenitors differ in length, those of the A genome species being longer than those of the D genome species. Furthermore, this size difference is maintained in the polyploid, in which chromosomes of two size-categories can be recognized. A histogram (Fig. 1) of the lengths of the somatic chromosomes from root-tips of seven plants of G. barbadense shows a bimodal distribution of the chromosome lengths and also indicates that there is a small overlap between the two groups.
