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 pro-
duced artificially. While cultivated rye varieties 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),
