Durum wheat[2] (/ˈdjʊərəm/), also called pasta wheat[3] or macaroni wheat (Triticum durum or Triticum turgidum subsp. durum),[4] is a tetraploid species of wheat.[5] It is the second most cultivated species of wheat after common wheat, although it represents only 5% to 8% of global wheat production.[6] It was developed by artificial selection of the domesticated emmer wheat strains formerly grown in Central Europe and the Near East around 7000 BC, which developed a naked, free-threshing form.[7] Like emmer, durum wheat is awned (with bristles). It is the predominant wheat that grows in the Middle East.

Durum in Latin means "hard", and the species is the hardest of all wheats. This refers to the resistance of the grain to milling, in particular of the starchy endosperm, causing dough made from its flour to be weak or "soft". This makes durum favorable for semolina and pasta and less practical for flour, which requires more work than with hexaploid wheats like common bread wheats. Despite its high protein content, durum is not a strong wheat in the sense of giving strength to dough through the formation of a gluten network. Durum contains 27% extractable wet gluten, about 3% higher than common wheat (T. aestivum L.).[8]
