Triticum aestivum
C tier
Triticum aestivum is common bread wheat, a hexaploid species that supplies most of the world’s milling wheat for loaves, cakes, pastries, and noodles. Kernel hardness, protein content, and gluten strength vary widely across winter and spring types and red and white classes, giving millers and bakers a broad quality spectrum from strong bread flours to tender soft wheat. Culinary use centres on flour and milled products: bread and pizza doughs, laminated pastries, cookies, crackers, steamed and boiled noodles, and whole-grain berries for porridge and salad. Bran, germ, and endosperm may be kept whole or separated; cracked, rolled, soaked, and fermented preparations extend the grain beyond straight milling.
Also known as: Hard red winter and spring bread wheats, High-protein spring bread wheat, Soft and hard milling classes for bread and pastry, Winter and spring wheat for noodles and steamed bread, Prime hard and soft export milling grades

History
Hexaploid bread wheat emerged in the Fertile Crescent from hybridisation of cultivated emmer with wild goatgrass, founding modern Triticum aestivum.
Bread wheat spread across Europe, North Africa, and Asia as a principal cereal for porridge, flatbreads, and early leavened loaves.
Linnaean taxonomy formalised Triticum aestivum as the scientific name for common wheat.
Industrial roller milling and New World expansion made Triticum aestivum the dominant global commodity flour crop.
Green Revolution semi-dwarf Triticum aestivum cultivars raised yields and reshaped international grain trade.
Genomic tools refined breeding for disease resistance, protein quality, and climate resilience in bread wheat.
