Durum wheat is a tetraploid species of wheat, scientifically classified as *Triticum turgidum* subsp. *durum*. It is the hardest wheat species and is best known as the main grain used to make semolina and pasta. Durum accounts for a small share of global wheat production but is economically important in dry-growing regions and pasta markets.

Description

Durum wheat is a hard, amber-coloured wheat species with a dense kernel and high gluten content. Its hardness makes it especially suitable for semolina milling and pasta production.

Cultivation and production

Durum is cultivated mainly in Mediterranean climates and other dry regions, including parts of Canada, the United States, Mexico, North Africa, and the Middle East. It represents a small but important portion of world wheat production, estimated at around 37 to 40 million tonnes per year.

Uses

The grain is used primarily for pasta because it yields high-quality semolina with good colour and cooking properties. It is also used for couscous, bulgur, and some breads.

Agronomic characteristics

Durum wheat is adapted to hot, dry conditions and is valued for its hard vitreous kernels and high protein content. These traits distinguish it from common bread wheat.

Key facts

  • Durum wheat is the second-most cultivated wheat species after common wheat.
  • It is generally grown in dry climates and is well adapted to Mediterranean-type conditions.
  • Most durum grain is milled into semolina, the coarse product used for pasta.
  • It is a tetraploid wheat with 28 chromosomes, unlike hexaploid common wheat.
  • Global production is commonly estimated at around 37 to 40 million tonnes per year.

Canadian context

Canada is one of the major producers of durum wheat, especially in the Prairie provinces, and Canadian durum is a significant export crop for pasta markets.

Frequently asked questions

What is durum wheat used for?
Durum wheat is used mainly to make semolina for pasta, and it is also used for couscous, bulgur, and some breads.
How is durum wheat different from bread wheat?
Durum wheat is tetraploid with 28 chromosomes, while common bread wheat is hexaploid. Durum is harder and is usually milled into semolina rather than standard flour.
Why is durum wheat called hard wheat?
The name comes from Latin *durum*, meaning “hard,” referring to its very hard kernel.
Where is durum wheat grown?
It is grown mainly in Mediterranean-type climates, including parts of southern Europe, North Africa, the Middle East, Canada, the United States, and Mexico.
How important is durum wheat globally?
Durum is a minor share of total wheat production, but it is a major crop for pasta and other durum-based foods.
