Taro and macabo are plants with high food, medicinal and economic value, but are under-utilized in Benin. The aim of this study was to identify local varieties of taro and macabo grown in Benin, with their vernacular names, farmers' recognition criteria and distribution. Data were collected between May 2021 and May 2023, through interviews using semi-structured questionnaires. The sample surveyed consisted of 349 taro/macabo producers, distributed in 40 villages belonging to 9 departments. The variables collected concerned producers' socio-demographic characteristics, local appellations, farmers' recognition criteria and the distribution of local varieties of the two species, and were processed by calculating relative citation frequencies and establishing a generalized linear model in R software. In addition, QGIS software was used to represent the distribution of the varieties surveyed. A total of 42 local appellations have been registered to designate all local varieties. Ten local varieties, including six of (V1 to V6) and four of (V7 to V10), were identified on the basis of seven (07) farmers' criteria, the main ones being tuber color (41.88 %) and leaf blade color (23.30 %). Local varieties V1, V3, V4 and V5 were the most widespread for , while varieties V7 and V9 were the most widely distributed from the south to the north of the country for . The socio-demographic parameters such as age category, occupation and ethnic groups tested had a significant influence (p < 0.05) on the number of local varieties held by growers. Agro-morphological characterization will provide data for the selection of elite varieties.
芋头和木薯是具有很高食用、药用和经济价值的植物，但在贝宁未得到充分利用。本研究的目的是识别在贝宁种植的芋头和木薯的当地品种，包括它们的土名、农民的识别标准和分布情况。2021年5月至2023年5月期间，通过使用半结构化问卷进行访谈收集数据。调查样本包括349名芋头/木薯生产者，分布在9个部门所属的40个村庄。收集的变量涉及生产者的社会人口特征、当地名称、农民的识别标准以及这两个物种当地品种的分布情况，并通过计算相对引用频率和在R软件中建立广义线性模型进行处理。此外，使用QGIS软件来展示所调查品种的分布情况。总共登记了42个当地名称来指代所有当地品种。根据七项农民标准识别出了10个当地品种，其中包括六个芋头品种（V1至V6）和四个木薯品种（V7至V10），主要标准是块茎颜色（41.88%）和叶片颜色（23.30%）。芋头的V1、V3、V4和V5品种分布最广，而木薯的V7和V9品种从该国南部到北部分布最广。所测试 的社会人口参数，如年龄类别、职业和族群，对种植者拥有的当地品种数量有显著影响（p < 0.05）。农业形态特征分析将为优良品种的选择提供数据。
