Tropical crops such as cowpea, yam, plantain, and cassava are heavily underresearched but, in addition to rice, maize, wheat, and potato, are important as primary or secondary food staples in the developing countries. The modern tools of molecular and cellular technology offer the opportunity not only to make substantial gains in knowledge of these crops, but also they overcome some of the obstacles which presently restrain both the genetic improvement and the productivity of these crops in tropical farming systems. Increased nutritional value of these crops, reduced post-harvest perishability, and lower costs of production are some of the advantages taken from biotechnology. Engineered genetic resistance would also allow to drastically reduce employment of pesticides, which at present are expensive or unavailable for farmers in developing countries and may create environmental and health hazards. In this book experts present opportunities to improve the efficiency of conventional plant breeding programs also taking into account the ethical and sociopolitical aspects of these technologies.

Recent advances in gene technology, plant transformation, and the growing knowledge of DNA sequences of plants as well as of their most important parasites and symbionts offer many interesting prospects for the breeding of new crop varieties. This was not only recognized by the major seed companies, but also by the governments of developing countries and by worldwide foundations supporting their agriculture. The know-how gained by the seed companies on crops important for the agricultural industry in developed countries could easily be provided for free to the international and national organizations dedicated to development of crops important in the third world. Results obtained worldwide become easily available to everybody through the scientific literature. Likewise, agricultural research in, e.g., the USA or Europe profits from the natural plant gene pool available in the third world. All this definitely provides for the possibility of fast change, new prosperity and security of food supply in the whole world, if properly applied. The fast development also asks for ethical and sociopolitical considerations, whereby not doing the right can be as much a mistake as doing the wrong.
