Abstract
The species of Phytophthora represent a gender of devastating pathogen of the vegetable ones and consequently they are the cause of important economic losses. In Cuba it is one of the fundamental problems that affect the cocoa production. The necessity to look for individuals genetically good and in turn that they are resistant to this disease it bore to the realization of this experiment, on a design totally randomized with 5 repetitions, in the Estación Experimental Agroforestal of Baracoa. The same one consisted on inoculating with a stump of the pathogen in semi-controlled conditions, 5 fruits of 25 agreements, for a period of 10 days, with the objective of determining the resistance degree in front of this disease. These individuals were previously studied by their genetic and morphological characteristics. The qualitative results, using the classification of severity showed that 16% was resistant, 8 % moderately resistant and 76 remaining % went susceptible to Phytophthora palmivora (Butl) Butl.
