Abstract
With the objective to evaluating the production stability of the cocoa hybrids cultivar descendants were planted in the Baracoa region on an Alluvial Humic Gleyed soil, at 28 meters over sea level. An experimental blocks design at random was used with five replicates. For the first four harvest and the one blunts it was evaluated: total number of ears, yield of dry cocoa and the half mass of the ears. For the last two harvests complementary evaluations of characterization of the hybrid were carried out that included: longitude of the fruit, wide of the fruit, and number average of seeds for ears and of the shell thickness. The climatic data were considered during the experimental period. The hybrid UF-650 x Pound-7 and UF-654 x Pound-7 presented good acting in the different years and they were considered as stable, with yields average of 1.12 and 1.02 t/ha, superior in a 18 and 16 % to the populational stocking, respectively. The hybrid UF-668 x Pound-12 and EET-400 x Sca-12 were unstable with yields accumulated average of 1.31 and 1.58 t/ha and with better behavior in favorable years.
