| Abstract: | Cassava hybrids from interspecific crosses with Manihot caerulescens Pohl, M. pseudoglaziovii Pax and Hoffmann and M. dichotoma Ule showed a very high iron and zinc content in both roots and leaves, e.g. 98.15 mg kg−1 in roots of the interspecific hybrid cassava-M. caerulescens versus 12.17 mg kg−1 in a cassava cultivar. This promising results show the potential of wild Manihot species for micronutrient enhancement of cassava. |
