Approximately only 30 cultivated plants provide the world supply of calories and proteins constituting more than 90% of the human diet. One of the strongest trends toward preserving global natural resources, which has the potential to reverse the current world food crisis involves the concept of sustainable agriculture. This concept allows for better use and protection of natural resources and more efficient management of materials for food production (e.g., fertilizers, pesticides, etc) toward the production of food in regions which are currently deficient with a minimum compromise of the environment. Plant diseases have always created a problem for food production worldwide. In the past fifteen years, a variety of plant diseases have threatened crops of great economic importance in México and in other Latin American countries. Research performed in Mexico has been responsible for greaty alleviating some of the compromise to agricultural production caused by these plant diseases. In the case of wheat, the stem rust was finally brought under control by the brilliant research achievements of Dr. Norman E. Borlaug and his team of Mexican scientists, who in 1970, received the Nobel Prize for World Peace. The agricultural research of this century has yielded enormous advances in plant breeding, in the use of soil and water, in the development of agricultural machinery for growing as well as harvesting crops. Now, however, the focus must be toward a more prudent use of chemicals in the name of global environmental integrity. The achievements of modern biotechnology through the use of special techniques such as tissue culture and genetic engineering contribute to an optimistic vision of world food production for the future of mankind. Two of the most important challenges for our country in the field of agricultural biotechnology are the upbringing of highly qualified human resources and the formation of research groups in touch with the problems that affect agricultural production.
