Yam bean a nearly forgotten crop
Date:9/14/2007

n by 50 to 100%. Several yam bean genotypes showed very low reduction in storage root and seed production under drought stressed conditions. As expected, the storage roots did show high protein and starch contents. They have as much as three to five times more protein than potatoes or yams. Most importantly, it was found that storage roots can be processed into yam bean gari. This is similar to the current staple of West Africa, cassava gari, a granular flour.

The bean could make a significant contribution to the improvement of food support, especially where resources are poor. The research is ongoing at the International Potato Center, which has a mandate for the bean in the frame of Andean Root and Tuber Crops. Further evaluation is needed on the range of yam bean variations under different conditions. More information on where they can be grown, their agronomic potential and genetic diversity is important to determine the types of breeding programs necessary for yam beans.
