Grain
Avena byzantina
B tier
Avena byzantina is red oat—a cultivated oat group adapted to warmer, drier conditions than typical sativa, with grain often showing reddish hull colour in covered forms. Food use exists but sativa dominates porridge markets; byzantina matters more in breeding and certain regional agricultures. Flavour when processed as food oats is still mild cereal-sweet. You may meet byzantina genetics inside modern cultivars rather than as a labelled retail oat. In species lists it marks the red oat lineage distinct from common white oats.

Crosses with sativa blended red oat traits into broader oat improvement.
Genetic resources of byzantina remained important for heat and disease traits.
