Start Date: Aug 19, 2013
End Date: Nov 28, 2015
At the present time, four field trials involving 6.0 hectares of land are part of the current CRIG/USDA SCA. The application of good agricultural practices such as maintenance of shade species, pruning of cacao trees, weed and ant control, cleaning of drainage system, fertilizer applications, and replanting of dead cacao plants with new seedlings will continue in the experimental areas during the new project period. Monthly evaluations of yield and disease incidence will also be recorded on a tree-by-tree basis in some of the trials as indicated below. In addition, new QTLs for resistance to BP and CSSV diseases will be identified using traditional mapping and association genetics. Validation of the efficiency of selection using the markers and using phenotypic data from field screenings will be completed.
