Modern soft wheat contains the complete genome of three different species, thus accumulating no fewer than 42 chromosomes through successive fusions and selections.<br> | ||
:Among the first representatives of wheat, wild varieties such as durum wheat and emmer were domesticated to give birth to soft wheat 9,000 years ago. The more widely cultivated soft wheat varieties develop a soft grain that is the origin of flour; durum wheat varieties, which are better adapted to dry climates, develop a hard grain adapted to the production of semolina.
