Pod corn

Pod corn
SpeciesZea mays
VarietyZea mays var. tunicata

Pod corn or wild maize is a variety of maize (corn).[1][2] It is not a wild ancestor of maize but rather a mutant that forms leaves around each kernel.[3]

Pod corn (tunicata Sturt) is not grown commercially, but it is preserved in some localities.[4]

Pod corn forms glumes around each kernel which is caused by a mutation at the Tunicate locus.[a] Because of its bizarre appearance, pod corn has had a religious significance to certain Native American tribes.[which?][5]

The six major types of corn are dent corn, flint corn, pod corn, popcorn, flour corn, and sweet corn.[6]
