THE STATUS OF CACAO (THEOBROMA-CACAO, STERCULIACEAE) IN THE WESTERN-HEMISPHERE

There are, at the present time, effectively no long-range, ongoing programs in any tropical country of the western hemisphere dedicated to the improvement of cacao (Theobroma cacao, Sterculiaceae). While some effort is currently made to obtain new acquisitions of cacao cultivars exhibiting desirable characteristics and to maintain genepools of these trees, there are few data from field trials to prove and substantiate these qualities. In addition, there is a growing concern regarding the disparities between predicted yields of cacao trees through the use of "hybrid" seed and from actual production under field conditions. This has stimulated an awareness of the current inadequate understanding of the genetics of cacao and the lack of comprehension as to which cultivars, under distinct ecological conditions, are precocious, resistant to disease, or heavy bearing, or indeed demonstrate those traits vital to the success of farming programs adapted to today's market conditions. This paper examines the events that have led to the current status of selection, development, and breeding of cacao. Alternative approaches are suggested.
