Biotechnology for Maize and Wheat Improvement in Developing Countries: a Need, a Reality, or a Dream?

  • David A. Hoisington
Part of the Plant Gene Research book series (GENE)


While the rate of increase in the world’s population is decreasing, up to two hundred people are still being added to the planet every minute. Over 90% of the increase is in developing countries (Swaminathan, 1995). It is forecast that by the year 2050, the world’s population may increase to over 8 billion people. To feed this population, these people will require a staggering increase in food production. It has been estimated that the world will need to produce more than twice as much food during the next 50 years as was produced since the beginning of agriculture 10,000 years ago!
