Selection of self-compatible progenies of high productivity cocoa in the Ecuadorian coast

Cocoa in Ecuador is one of the main crops economic importance, mainly for small and medium farmers on coast. Sexual self-compatibility most important criteria selection clonal plants from members hybrid progeny. Trees with higher levels are those that tend to produce earlier compared self-compatible ones. The study consisted selecting 333 trees a group 71 progenies, based such as productivity health during 5 years evaluation (2002-2007) thus determining level per individual within progenies. cocoa, estimate progeny under its relationship yield select high productivity. Binomial test was used, which determined minimum 30% successful pollinations. 0.05% probability considered compatibility threshold each tree. For at least 70% their individuals must present this characteristic, data were recorded three, seven fifteen days respectively, order have more precision process fruit initial development performance. results showed there wide variability regarding all studied families. Only 3 families had sufficient number be classified likewise. However, average performance not necessarily superior other self-compatible. On hand, it could also confirmed tree, clone or cross can change percentage fertilization according time environmental conditions.
