Cocoa farming is one of the most important activities in the Peruvian Amazon. Its genetic basis is supported by the introduction of improved clones, so that the local genetic potential are in germplasm bank is not well used due to limited breeding study. This study aimed to estimate the repeatability for the genetic selection of high-yield trees with aromatic cocoa beans. Genetic selection analysis was executed with the SOFTWARE SELEGEN REML / BLUP in a 3-year data for assessing grain yield kg / tree, average grain weight (g) and average weight of cobs (kg) in the bank germplasm INIA-San Martin and Lebuaf Conservation Unit SAC (Plantation Maria). The individual repeatability grain yield / tree and average grain weight was moderate (0.52) and (0.30) respectively, which did not happen for the repeatability of the variable average cob weight was low with (0.24). The variable was more stable...

El cultivo de cacao, es una de las actividades más importantes en la Amazonía Peruana. Su base genética está sustentada en la introducción de clones mejorados, por lo que el potencial genético local que están en los bancos de germoplasma no está siendo bien utilizados debido al limitado estudio en mejoramiento genético. Este trabajo tuvo por objetivo estimar la repetibilidad para la selección genética de árboles con alto rendimiento de granos de cacao aromático. El análisis de selección genética fue ejecutado con el software SELEGEN REML/BLUP, en una data de 3 años de evaluación de rendimiento de granos kg/árbol, peso promedio de granos (g) y peso promedio de mazorcas (kg) en el banco de Germoplasma de INIA-San Martin y Unidad de Conservación de Lebuaf SAC. La repetibilidad individual para rendimiento de granos/árbol y peso promedio de granos fue moderada con (0,52) ...
