Abstract:
Morphological characteristics of yam and farmers’ perceptions is one of the factors necessary to
improve and promote the cultivated yam. The aim of this study is to describe the current status
and farmers’ knowledge of yam on Idjwi Island. A total of three species of yam were recorded.
Species of yam are commonly nominated Biriga, but farmers’ give names to yam landraces
based on the shape, size and color of tubers and productivity. However, the landraces were
benefit for producers who sell their most important production in town. Also, this study revealed
the existence of one morphological group within yam species as shown by morphometric
measurements. These results shown that it’s important to improve yam production in this region
in order to create a food diversification. |
