| description | The objective of this research was to evaluate the germinability of seeds and the initial development of interclonal hybrids of Theobroma cacao L. The trial was established in the experimental campus "La Teodomira", Manabí, Ecuador. Intraspecific crosses were made between five genotypes of T. cacao, the fruits obtained were harvested at approximately 180 days. The variables studied were: germination and emergence percentage, plant height, stem diameter, number of leaves and chlorophyll content in the leaf area. A 97.8% germination was obtained at eight days after demulization and imbibition and an 86.5% emergence, registering a higher percentage of germination and emergence in the progeny derived from the L11-H19 x EET-103 cross. At 120 days, the greatest stem diameter was recorded in the EET-558 x CCN-5 family and the greatest height in the EET-103 x L11-H19 family. On average, 15 leaves per plant and 43.5 of SPAD chlorophyll were obtained at 120 days. The chlorophyll content in the leaves is determined by the physiological age of the seedlings. However, for future research it is recommended to carry out field evaluation of these progenies, especially of physiological aspects involved with the production of leaves and chlorophyll content, since these could be indicators for the selection of promising genotypes |

El ensayo se estableció en el campus experimental “La Teodomira”, Manabí, Ecuador. Se realizaron cruzamientos intraespecíficos entre cinco genotipos de T. cacao, los frutos obtenidos se cosecharon aproximadamente a los 180 días. Las variables estudiadas fueron: porcentaje de germinación y de emergencia, altura de planta, diámetro de tallo, número de hojas y contenido de clorofila en el área foliar. Se obtuvo un 97.8% de germinación a los ocho días luego de desmulización e imbibición y un 86.5% de emergencia, registrándose un mayor porcentaje de germinación y emergencia en la progenie derivada del cruce L11-H19 x EET-103. A los 120 días, el mayor diámetro de tallo se registró en la familia EET-558 x CCN-51 y la mayor altura en la familia EET-103 x L11-H19. En promedio se obtuvo 15 hojas por planta y 43.5 de clorofila SPAD a los 120 días. El contenido de clorofila en las hojas está condicionado por la edad fisiológica de las plántulas; no obstante, para futuras investigaciones se recomienda realizar evaluación en campo de estas progenies, en especial de aspectos fisiológicos involucrados con la producción de hojas y contenido de clorofila, pues estos podrían ser indicadores para selección de genotipos promisoriosUniversidad Técnica Estatal de Quevedo2020-12-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://revistas.uteq.edu.ec/index.php/cyt/article/view/39010.18779/cyt.v13i2.390Ciencia y Tecnología; Vol. 13 No. 2 (2020): Science and Technology July - December 2020; 31-38Ciencia y Tecnología; Vol. 13 Núm. 2 (2020): Revista Ciencia y Tecnología Julio - Diciembre 2020; 31-38Ciencia y Tecnología; v. 13 n. 2 (2020): Revista Ciencia y Tecnología Julio - Diciembre 2020; 31-381390-40431390-405110.18779/cyt.v13i2reponame:Revista Ciencia y Tecnologíainstname:Universidad Técnica Estatal de Quevedoinstacron:UTEQspahttps://revistas.uteq.edu.ec/index.php/cyt/article/view/390/461https://revistas.uteq.edu.ec/index.php/cyt/article/view/390/462Derechos de autor 2021 Ciencia y Tecnologíainfo:eu-repo/semantics/openAccess2021-02-25T02:24:20Zoai:revistas.uteq.edu.ec:article/390Portal de revistashttps://revistas.uteq.edu.ec/index.php/cytUniversidad públicahttps://www.uteq.edu.ecEcuadorCiencia y tecnología1390-40431390-4043opendoar:2021-02-25T02:24:20falsePortal de revistashttps://revistas.uteq.edu.ec/index.php/cytUniversidad públicahttps://www.uteq.edu.ecEcuadorCiencia y tecnología1390-40431390-4043opendoar:2021-02-25T02:24:20Revista Ciencia y Tecnología - Universidad Técnica Estatal de Quevedofalse |
