Dent Corn Cultivation

Emmer wheat (Triticum turgidum) was the precursor for the durum wheat (Triticum turgidum var.durum) that is grown today.

Wheat ended up replacing barley because it is more easily extracted from the leaf-like hulls and can be made into bread.

Spanish explorers introduced wheat into North America in the 1500s, and it was grown in the New England colonies in the early 1600s.
