Figure 8.D The CIYMMT headquarters The Centre International de Mejorimiento de Maiz yTrigo (CIMMYT)
(International Center for the Improvement of Maize and Wheat) in Texcocu, Mexico, is involved in
plant breeding and research. High-yield-variety seeds were developed here for the Green Revolution.
The center holds the world's premiere collection of corn and wheat germplasm. Modern, refrigerated
storage vaults store many thousands or" varieties. Today, in addition to the static, cold storage,
scientists are working with farmers to preserve seeds dynamically.







Figure 8.E Green revolution experimental plots The CIMMYT includes numerous plots for breeding and
testing seed varieties.

Figure 8.F Global distribution of maize production The widespread production of grains throughout
the globe, particularly maize, has been one of the successes of the green revolution (After J. P.
