A grain of wheat, the most primitive cultivated species in the wheat genus. Originating from Asia Minor. The ears are small, uniform, and extremely tight, often with broad spikes on the sides and narrow spikes on the front. The cob is brittle and easy to break. Each spikelet often has only one awn flower that bears fruit, and the lemma splits vertically into two pieces when the grain matures. The spikelets are tightly packed, making it difficult for the wheat grain to fall late. Late ripening results in extremely poor yield and quality. Can be used as raw material for wheat hybrid breeding.
