CLASSIFICATION


Rye (Secale cerealeL.), member of the grass family (Gramineae)
and typically classified into winter and spring varieties, is a
diploid, seven-pair chromosome cereal, with tetraploid varieties
sometimes being produced artificially. While cultivated rye va-
rieties are less numerous than those of other cereal crops, most
varieties are mixed populations because of cross-pollination.

PRODUCTION


Although rye production (15 million tons) is low compared with
the 2003 total world production of the three major cereals, wheat,
corn, and rice (556, 638, and 589 million tons, respectively)
(FAO 2004), rye’s low soil and fertilization requirements as well
as its relatively good overwintering ability guarantee continuing
interest in the cereal, as it can be cultivated in areas generally not
suited for other cereal crops. In 2003, high amounts of rye were
produced by Russia (4.1 million tons), Poland (3.2 million tons),
Germany (2.3 million tons), and Belarus (1.4 million tons) (FAO
2004), making this cereal crop of major importance in parts of
