The American Story of Corn
Episode 2:
Walter Goldstein –
Mandaamin
Institute
A Partnership Between People and Plants
Corn breeder and researcher Walter Goldstein traces the long arc of corn’s evolution, from its Indigenous origins to modern breeding challenges. He explores corn’s deep history on the American continent, a story of the living relationship between people and plants. Walter describes his work at the Mandaamin Institute, where he breeds corn for organic farming with desirable qualities: high nutritional value, nitrogen-fixing capability through a relationship with bacteria, and resistance to GMO pollination. These excerpts are taken from Walter’s 2016 presentation at the American Dream Conference, hosted by the MaaViva Institute.
