摘要:Cassava Manihot esculenta Crantz was present in Brazil even before the colonization process, historically known as the bread of the land is cultivated primarily by small farmers in traditional communities who adapt as management and cultivation technicians of the species according to the soil and characteristics. local climate. Cassava has characteristics of high energy potential and ease of climate adaptation, so it is widely cultivated throughout the Brazilian territory, having in turn a great genetic variability, a relevant diversity of ethnovarities, representing important genetic resources for its preservation and conservation. be used in genetic improvement with emphasis on the transfer of quantitative genes, a genetic importance of cassava is related to the large number of ethnovarities cultivated by traditional communities, employing the ethnoknowledge built over generations. Thus, we sought to characterize as main ethnovarities of cassava grown in the community Sítio Santo Antnio in Beberibe, Ceará, considering the traditional knowledge and agromorphological descriptors according to the pertinent literature. For that, observation techniques were used, informing with a semi-structured script, structured questionnaire, field notes diary and collection of ethnovarities for characterization according to descriptors. Five ethnovarities were identified, named as purple cassava, paulista, queen of the sky, green eye and fragoza. The green eye ethnovariety presents the character of growth / height of better development as identified varieties, the root of this variety presents the robust development of large size, important for the production of dry flour.
