Comparative sporulation as an indication of resistance by cacao to Phytophthora pod rot
Phytophthora palmivora inoculated into detached immature cacao pods generally produced significantly fewer sporangia on pods of selections with high resistance to pod rot than on pods of varieties less resistant or susceptible. These differences, the causes of which are unknown, did not extend to lesions in mature tissues. The results suggested a correlation between sporulation levels and periods of high disease incidence. Comparative sporulation may be, in conjunction with other criteria, a useful and rapid indicator of resistance in laboratory tests on existing and new cacao selections.
