Rye, the well-known species of Secale cereale, a grass which probably is from western Asia. It closely resembles and is related to wheat. It is a hardy grain and is grown in cool regions. In northern Europe it is a most important crop, being used there largely in bread-making. In the United States it is used chiefly in the manufacture of malt and spirituous liquors. Russia produces the most rye, her crop in 1910 being 867,622,000 bushels, Germany coming second with 413,802,000 bushels. In the United States rye is fifth of the cereals in importance, the crop of 1910 being 33,039,000 bushels.
