Orphan crops are a diverse set of minor crops like tef, finger millet, yam,
roots and tubers that tend to be regionally important but not traded around the
world and receive no attention by research networks.
Developing countries however rely on these crops more heavily than rice and
wheat that are researched heavily by private corporations.
