ABSTRACT
As for all plant species, at the beginning of the twentieth century hemp breeding was in advance of genetics. Dewey (1927) bred excel lent late-maturing varieties from Chinese landraces (Kymington, Chington, and Arlington), while in one of his varieties he used the Italian landrace Ferrara as one of the parents, as indicated in its name (Ferramington). Dewey can be regarded as the first hemp breeder. In wide spacing his varieties reached a height of as m uch as 6 m. Unfor tunately, due to the hemp production prohibition introduced in the United States, his varieties have been lost.
