Amino Acid Resources of the Wild Relative of Barley ( Hordeum spontaneum ) in Israel

Measurements were made on amino acid contents in collection of wild barley ( Hordeum spontaneum )., grown in pot conditions, and in some Israeli breeding lines and cultivars of Hordeum vulgare. H. spontaneum was low in lysine content and high in prolilne plus glutamic acid compared to H. vulgare. Lysine content was positively correlated, in H. spontaneum , to all other ammo acids except proline and giutamic acid. Inter‐populanon rnean differences for Iv‐saie in H. spontaneum were small and lysine variation was obscured due to variation in protein content. The use of H. spomancum in breeding high protein. nutritionally improved barley is discussed.
