Most of the area sown to maize (58 percent) is in developing countries, and of this approximately 50 million hectares are in the tropics, mainly at low elevations. However, about two-thirds of the world's maize is produced in developed countries, whose climates are almost entirely temperate. Production figures show large differences in yield between developed countries in temperate regions and developing countries in the tropics. The physiological understanding of the limitations to grain yield provide a basis for crop improvement, but there are few examples of recurrent selection based on physiological characters that determine yield. Maize has an important part to play in providing food to meet the current and future needs of the world. As a species it contains enormous genetic variation. The potential yield of maize is larger than that of either wheat or rice and, as we look toward the year 2000, we can expect maize to assume a proportionally larger and more important role in world food production.

A Maize Kernel Visit the page of the Cooperative Federal-State Maize Breeding Project at Iowa State University. Learn about the researchers and their research projects in various fields, including: population improvement, inbred releases, quantitative genetics, molecular markers, QTL mapping, exotic germplasm and the molecular biology and biochemistry of grain quality of maize. Some papers and data can be downloaded in PDF format, and some presentations can be reviewed on-line. As examples, see the paper by Lamkey and Edwards (1998) on The Quantitative Genetics of Heterosis, and Labate's (1997) presentation on Population Genetic Analysis of Molecular Marker Data
