Popis:	The potential development of the four varieties of yam the most commonly cultivated in Madagascar, Dioscorea esculenta (Lour), and Dioscorea alata L. cv ovibe, ovilalaina, ovifotsy were determined in this study. A hedonic test showed the main effect of consumer origin and age as well as an interaction between the two factors. Regardless of age, consumers from yam regions preferred yams more than did consumers from regions where yams are not cultivated. In the latter regions, adult consumers preferred yams more than did children. Besides these differences in global appreciation of yams, D. esculenta (Lour) and the ovilalaina cultivar obtained the highest preference scores from all consumers. A descriptive test and physicochemical measures indicate that D. esculenta (Lour) and the ovilalaina cultivar contain more carbohydrates, starch and calories and are described as sweet and easy to swallow. Sweetness seems to be particularly sought by children from regions where yams are not cultivated.
