The development of hybrid corn technology in the United States and selected countries

"A presentation of the background and recent developments of the new high-yielding, more nutritive corn types and an explanation of their significance to malnourished populations of countries deficient in food. This new high lysine (an amino acid) corn out-yields native corn types and has more than doubled the nutritive value of ordinary corn with protein quality essentially equal to that of skim milk. Worldwide development and acceptance have been relatively rapid. Unlike ordinary corn, these new types are not deficient in two essential amino acids -- lysine and trytophan. Shortages of these amino acids in the diet of humans (and other monogastric animals) cause serious protein-deficiency diseases, and utilization of the new high-lysine corn types can be a major means of combating this form of malnutrition."--Bibliographic input sheet, Agency for International Development.
