Simple techniques developed for rooting stem cuttings of sapogenin-bearing yams were tested with edible species and their varieties. Rooting began within 5 weeks after initiation of treatment or not at all. Species and varietal differences were evident. Cuttings of most D. alata varieties root freely, those of D. rutundata are intermediate, and those of D. esculenta and D. trifida are very difficult to root. Cuttings taken early in the season develop roots and shoots readily, but those taken later develop a small tuber and roots but often do not develop shoots. Very young cuttings or cuttings from the mature stem do not root as easily as cuttings of intermediate age.
