Resúmenes
Suspensions of Crinipellis perniciosa basidiospores were sprayed on cacao plants with young vegetative flushes and incubated for 24 hr in a dew chamber at 25 centigrade grade. Significant differences in resistance among progeny from putative resistant and susceptible clones were detected with suspensions containing 10,000-12,500 basidiospores/ml, higher spore concentrations resulted in similar disease incidence on resistant and susceptible families. Basidiospores collected overnight in 15-16 percent glycerol solutions and stored for 0 (fresh) and 18 months in liquid nitrogen produced similar percentages of disease on inoculated seedlings
