Seeds for economically important crops are big business indeed. As large seed companies continue to improve their product in various ways, they make use of the original gene pools of these plants, often located in tropical and subtropical areas of the world. With increasing recognition that plant germplasm is an important raw material, highly charged international disputes have developed over the exchange and use of this material, adding another point of contention between poor nations and the manufacturing wealthier ones.

Twenty experts from several nations, representing both the natural and social sciences, consider the historical background, the issue of patent rights as applied to plant germplasm, the nature of global genetic interdependence, the internationalization of the seed industry, the implications of biotechnology on genetic resources, the Third World attitude toward the debate, and the viewpoints of the International Agricultural Research Centers.
