摘要：Banana and plantain are popular fruits considered as major staple foods, and provide significant income to farming communities. A handicap to their development and production remains access to quality suckers. However, their diversity is still unknown in Benin. To assess the knowledge on the diversity of local varieties of both dessert banana and plantain at the community level, ethnobotanical surveys were undertaken using participatory research appraisal tools such as direct observations, group discussions and field visits from 119 interviewees living in 63 villages from 24 communes districts in Central and South of Benin. A total of 121 farmer-named banana and plantain varieties (83 vernacular names for banana and 39 others for plantains) were recorded and gathered into 58 differentiated varieties on the basis of the significance of the vernacular name relying on morphological traits and medicinal uses. Southern ethnic groups hold higher local varieties (H = 3.15 bits for the ethnic group Fon and H = 2.09 bits for Wemegbé) due to the high rainfall conditions favorable for the development of banana species than those from Central-Benin (H = 0.64 bits for the sociocultural group Mahi). The main constraints to these crop productions were drought (23.8% of responses), stealing of the whole bunch (19.0%), pests and diseases (14.3%), susceptibility to flood (9.5%) and pseudostem break by wind (7.8%). In situ and ex situ conservation should be undertaken to preserve the varieties cultivated by a few households on small areas defining their vulnerability status as well as those most commonly produced in large amounts.
