| dc.description | SUMMARY This work was carried out in the province of Los Ríos (Ecuador) in the cantons: , Babahoyo and , with the aim of morphologically characterizing the National type cocoa production areas (Theobroma cacao L.). We worked with a population of 150 national type cocoa trees. For this research, a specific list of 32 variables was used, taking as reference morphological and agronomic descriptors for cocoa from the Cocoa Research Unit University of West Indians (University of the West Indies 2015). Conglomerate and correlation analyzes were performed to identify and study the differences and similarities between subgroups within the National type cocoa. As results, it was possible to demonstrate the stability of the morphological characters since there were no phenotypic differences in the evaluated cocoa individuals, since over 80% of the evaluated variables did not exceed a CV> 50%, which indicates that the species it had little variability among the evaluated population. Regarding the correlation coefficient, the results show a relationship between the variables where it could be determined that they are related as the number of branches with leaf blade width; Similarly, a relationship between the number of leaf-shaped branches was evident. In the case of the cluster analysis, the result of this analysis allowed grouping, by similarity of their characteristics, the trees evaluated into 4 classes I (blue), II (yellow) III (green), IV (red). | es_ES |

| dc.description.abstract | RESUMEN Este trabajo se realizó en la provincia de Los Ríos (Ecuador) en los cantones: , Babahoyo y , con el objetivo de caracterizar morfológicamente las zonas de producción de cacao (Theobroma cacao L.) tipo Nacional. Se trabajó con una población de 150 árboles de cacao tipo nacional. Para esta investigación se utilizaron una lista específica de 32 variables, tomando como referencia descriptores morfológicos y agronómicos para el cacao de la Cocoa Research Unit University of West Indians. Se realizaron análisis de correlaciones y conglomerados para identificar y estudiar las diferencias y semejanzas entre subgrupos dentro del cacao tipo Nacional. Como resultados se pudo evidenciar la estabilidad de los caracteres morfológicos ya que qué no existieron diferencias fenotípicas en los individuos evaluados de cacao, ya que sobre el 80 % de las variables evaluadas no superaron un CV > al 50 %, lo que indica que la especie tuvo escasa variabilidad entre la población evaluada. Con respecto al coeficiente de correlación, los resultados muestran relación entre las variables en donde se pudo determinar que se relacionan como número de ramas con ancho de lámina foliar; De igual forma se evidencio relación entre número de ramas con forma de la hoja. En el caso del análisis de conglomerados, el resultado de este análisis permitió agrupar, por similitud de sus características, a los árboles evaluados en 4 clases I (azul), II (amarillo) III (verde), IV (rojo). | es_ES |
