Abstract

104 words

Cocoyam accessions of Malawi were characterised using ethnobotany and morphological characters. Thirty above ground qualitative characters were evaluated. The cultivars were identified mainly based on the predominant leaf base and petiole attachment. The study revealed farmers’ preferences of cocoyam varieties of interest to them. These included uses of plant parts for food, livestock feed, medicine, ornamental and adaptation to different agro-ecologies. The study further revealed significant amount of cocoyam diversity in Malawi. Farmers maintaining this diversity also hold rich ethno-botanical and ecological knowledge of the cocoyam cultivars that they are conserving. A thorough collection country wide and a complete agro-morphological evaluation study are recommended.
