Characteristics of oats
Oats belong to Gramineae and can be divided into hulled oats and hullless oats. Oats with skins are mainly used as feed and forage grass, and naked oats can be used as grain, feed and forage grass. Oats grown in China are mainly hullless oats, and we usually eat naked oats.
Spikelets contain 1 to 2 florets, and the spikelet axis is close to hairless or sparse short hair, which is not easy to break. The back of the first lemma is hairless, the basal plate has only a few short hairs or nearly hairless awns, or only the back has 1 straight awns, and the second lemma is hairless and usually awnless. There are great genetic differences in plant height, ear traits and grain traits of common cultivated oat varieties in China.
