Regional evaluations of US and semi‐exotic maize ( Zea mays L .) varieties identified three semi‐exotic Corn Belt varieties [‘BSTL,’ ‘BS2,’ and ‘PHWI(MI)C7’] and two semi‐exotic Southern varieties [‘PHWI(MT)C7’ and ‘(Indian Chief ✕ Diente de Caballo)(S)C2’] that approach exceed the performance of US varieties. Two decades or more breeding were required to develop them as tential breeding populations as sources for the development of hybrids. These semi‐exotic varieties may be potential sources of genetic resistance to insects and diseases including southern leaf blight ( Helminthosporium maydis ).
