Technical Abstract: We used a microbial assay to measure folate levels in mature tubers from ~80 different cultivars and wild species. We found about a 3-fold difference in folate concentrations between tubers with the lowest and highest concentrations. Of the top 10 varieties, 7 were yellow fleshed, 2 were red fleshed and one was white fleshed. No wild species was in the top 10, however, the wild species appeared to have a greater range of folate concentrations than the cultivars, which suggests we should examine more wild species.
