Notes
The USDA-ARS Tropical Agriculture Research Station's Theobroma cacao collection was field characterized in Mayaguez, PR over five years (2007-2011).
Characterization efforts focused on highly discriminating phenotypic traits in addition to agronomic traits of importance (e.g., length, width and weight of pods, diseased pods and pod index) and these were recorded for all accessions being evaluated. Cacao trees were established in a randomized complete block design in 2001 in a full sun, irrigated, pruned, fertilized and highly managed orchard. Trees were planted in a diamond pattern with two meters between trees and rows with a three meter alley between every second row for equipment. All accessions were grafted onto Amelonado rootstock. Evaluations began in 2007, when the trees were approximately six years old. Both phenotypic and agronomic traits were measured in an attempt to efficiently distinguish among genetically similar clonally propagated accessions as well as to identify some of the accessions with promising agronomic potential.
