Bean yields in Latin America have not improved in the last decade. Production increases resulting from greater area planted lag behind population changes, decreasing bean availability and forcing prices upward. This article discusses the major disease, insect, varietal and agronomic restraints to higher bean yield in Latin America, and reviews possible breeding and research strategies to limit them. It is suggested that improved yields in a subsistence crop such as beans, which is commonly grown under rainfed conditions and with limited technical inputs, may require different priorities and approaches from those used so successfully in wheat and rice.
