This study focuses on four yam cultivars belonging to the Folou or Flado farmer’s group in the Gourounsi and Lobiri national languages grown in Burkina Faso. Its objective is to describe the different yam cultivars belonging to this group. To this end, 27 qualitative variables, including ten (10) for the stems, nine (9) for the leaves, five (5) for the tubers and three (3) for the flowers, were selected to characterize the varietal group. The trial was conducted in a Fisher block design with three replications. The work was conducted during the 2019-2020 and 2020-2021 rainy seasons in the village of Onliassan, Sissili province. The study revealed that the Folou or Flado varietal group can be attached to the D. alata species and would consist of five (05) cultivars instead of three (03) previously described by farmers.
