The phenotypic behavior of cocoa fruit is regulated by environmental conditions of temperature, solar radiation, precipitation and relative humidity. Cocoa fruit grows in tropical conditions, therefore this research work was carried out on 8-year-old plants at Palmas del Espino S.A. located in the district of Uchiza. The objective was to determine the phenotypic behavior of cocoa fruit (Theobroma cacao L.) clone CCN-51, under environmental conditions. The design used was non-parametric analysis of variance with the Kruskal Wallis test and multivariate technique of principal components (PCA). Biometric variables were evaluated: length, fruit diameter, seed index, pod index and dry bean index, and climatic variables: temperature, solar radiation, precipitation and relative humidity. It was found that cocoa for fruit weight (704.25 g - 888.03 g) and seed index (1.30 g - 1.60 g) values increase with higher temperature and solar radiation. The fruit diameter (97.09 mm - 103.08 mm) indicates that higher values are strongly related to temperature and solar radiation, with a lesser but also important influence of precipitation and relative humidity. A negative relationship was observed between precipitation and dry grain index (32.00 % - 34.80 %), which means that the higher the precipitation, the lower the dry grain index. The time of fruit development (167 days - 173 days) is influenced by temperature, which determines between a short and long period to reach harvest ripening of the fruit. The direct relationship between pod index and seed index was also observed
