Résumé : The consumer testing for pounded yam was conducted in rural and urban areas of Ebonyi State, South-East Nigeria with 150 consumers disaggregated into 70 women and 80 men. The variety names and code numbers used in parentheses include; TDA 1100477 (289), TDA 1100203 (463), TDR 1100497 (135), and TDR 11/0010 (721). The urban areas were Onueke and Abakaliki; rural (Amagu Izzi and Umuebe Ezzamgbo) and the small town was Nkwagu). Majority of the respondents were civil servants (44.7%), and married (52.7%). Many consumers interviewed consumed the product once a month (32.0%), 30% consumed the product several times a week,14% once a week, while 13% consume it several times a month and and about 11% daily. Consumption frequency indicates that yam consumption in the form of pounded yam is an important menu in the diet of people in the study area. Agglomerative Hierarchical Clustering analysis of the mean overall liking scores, identified four groups of consumers that include; “TDA 1100203 and TDR 1100497 likers” (8%), “TDA 1100477 dislikers” (26%), “all likers” (45%) and “TDR 1100497 dislikers” (21%). There were significant differences (Chi-square; p < 0.001) in the overall liking of the three clusters with regards to sociodemographic characteristics. The most liked product sample was TDA 1100203, because it was 'easy to swallow', 'easy to cut', 'mouldable' and had a 'good aroma', followed by TDR 1100497 described as 'sweet taste', 'not sticky', 'smooth', and with 'no lumps', and TDR 11/0010 because it is 'easy to pound', 'heavy weight', 'drawy' (stretchy), starchy and the least liked TDA 1100477. The least preferred traits include; 'lumps', 'sticky', 'dull/dark colour', 'not drawy', 'too soft', and 'bad colour'.
