Wheat Taxonomy

Reclassification of Triticum according to Löve 1984, with nomenclatural corrections.

The 1984 Löve classification [reference] was part of a taxonomic revision of the Tribe Triticeae. Following a broad interpretation of the biological species concept, Löve defined genera by their unique genome constitution, either as genera of diploids or polyploids. Thus, the genus Triticum was split into three genera, each corresponding to one of three ploidy levels in the genus.
