Barley (Hordeum vulgare) is one of the most important cereals and belongs to the family of sweet grasses.

The barley spikes have long beards which are inclining or hanging when getting mature. As the spikes show different characteristics, barley is distinguished in two-and multi-line sorts. In the case of the two- line barley only one grain is developed, which is highly developed. The multi-row barley generates up to three weaker grains per assay point.

Two-row barley (mostly summer barley) is mainly used for brewing purposes. Summer barley, which is not suitable for malting, can then be used as peeling barley. Row barley (often winter barley) generates higher yields and is often used as animal feed.
