Suspensions of Crinipellis perniciosa basidiospores were sprayed on cacao plants with young vegetative flushes and incubated for 24 hr in a mist or humidity chamber. Significant differences in resistance among cacao families were detected with inoculum concentrations of 25.000-150,000 basidiospores/ml. The hybrid between two clones reported as resistant (Silecia 1 and ICS 6) had the lowest percentage of disease. Intermediate or high percentages of disease were observed in hybrids between susceptible X resistant (Tenguel 33 X Silecia 1) and susceptible X moderately resistant (Tenguel 15 X IMC 67), respectively. Differences in resistance among 4-year-old trees inoculated in the field were also detected
