AGUDELO-CASTANEDA, Genaro Andrés et al. New cocoa varieties selected in Colombia. Rev. Mex. Cienc. Agríc [online]. 2023, vol.14, n.3, pp.315-326.  Epub 19-Jun-2023. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v14i3.3057.

In recent years, the increasing cultivation of cocoa in Colombia has been consolidated into the country's agricultural economy, requiring further technological developments to improve productivity and profitability. Lack of genotypes and adapted and selected productive varieties is one of the causes for low yield. The aim of this study is the agronomic evaluation of eight cocoa genotypes TCS13, TCS19 (Theobroma Corpoica La Suiza), SCC53, SCC82, SCC83 (Selección Colombia Corpoica) and CCS 73, CCS77, CCS80 (Colección Corpoica La Suiza), compared to a commercial control ICS95 (Imperial Collage Selection), in four producing localities within the natural subregions of Montaña Santandereana and Magdalena Medio in northeastern Colombia, established in agroforestry systems with fine woods. The results identified two genotypes- TCS13 and TCS19- which were superior in yield (with production of 1.5 and 1.8 kg tree-1 year-1, respectively), low incidence of limiting diseases such as Frosty Pod Rot, and self-compatible. These results allowed the inclusion in the national registry of commercial cultivars in the Colombian Agricultural Institute (ICA) in 2017.
