| description | The agroecological diversity in which coffee bean production develops in Ecuador makes it possible to do research concerning the identification of more productive genotypes in specific production regions. The main objective of this study was to determine the agronomical, productive and sanitary characteristics of different genotypes from the Germplasm Bank of the Robusta coffee variety at EETP-INIAP. Statistical techniques were used for identifying more productive genotypes with the aim of selecting ‘clone heads’ inside and between genetically diverse accessions with features of commercial interest under environmental conditions of the humid tropic and rainfed settings. Our results showed a significant positive correlation (P<0,05) between production and other plant characteristics such as stem diameter, total branches, productive branches, branch length and number of nodes. In respect to crop production, COF-001 was observed to be similar to NP 3018. We found few differences between NP-3056 and NP-3018 and COF-01. NP-2024 was similar to COF-005. COF 004 was similar to COF-005. COF-002 and NP-2044 were different from other individuals. A total of 4 genotypes (COF-004, NP-2024, COF-003, NP-4024) were selected and recommended for commercial consideration under polyclonal farming, all of them reporting average yields above 7000 kg coffee beans/ha, along with good agronomical characteristics and pest resistance. |

Bajo esta premisa, el presente trabajo tuvo como objetivo central determinar el comportamiento agronómico, productivo y sanitario de los genotipos que conforman el banco de germoplasma de café robusta de la EETP-INIAP; para identificar y seleccionar individuos superiores en las condiciones ambientales del trópicohúmedo, en condiciones de secano. Se aplicaron técnicas estadísticas que permitieron identificar genotipos superiores, para seleccionar “cabezas de clon”, dentro y entre accesiones genéticamente diversas y con características de interés comercial. Los resultados obtenidos mostraron correlación positiva (P<0,05) entre la producción y los caracteres de diámetro del tallo, ramas total, ramas productivas, longitud de rama y número de nudos. El COF-001 resultó similar a NP 3018; NP-3056 tiene pocas diferencias con NP-3018 y COF-001;NP-2024 es similar a COF-005; COF 004 es parecido al COF-005; COF-002 y NP-2044 son distintos a los demás materiales. Un total de cuatro genotipos fueron seleccionados para su recomendación comercial bajo un sistema de siembra policlonal: árbol 15 del COF-004, árbol 10 de NP-2024, árbol 15 del COF-003 y árbol 4 de NP-4024, los cuales, reportan rendimientos promedios de 70 qq de café oro/ ha-1, buenas características agronómicas y tolerancia a plagas y enfermedades.Escuela Superior Politécnica Agropecuaria de Manabí Manuel Félix López2015-06-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtículo revisado por paresapplication/pdftext/htmlapplication/ziphttps://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/90Revista ESPAMCIENCIA; Vol. 6 Núm. 1 (2015): REVISTA ESPAMCIENCIA 2015; 7-131390-8103reponame:Revistas Escuela Superior Politécnica Agropecuaria de Manabíinstname:Escuela Superior Politécnica Agropecuaria de Manabíinstacron:ESPAMspahttps://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/90/73https://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/90/742https://revistasespam.espam.edu.ec/index.php/Revista_ESPAMCIENCIA/article/view/90/743http://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccess2025-02-25T14:32:02Zoai:espamciencia.espam.edu.ec:article/90Institucionalhttp://revistasespam.espam.edu.ec/Universidad públicahttp://www.espam.edu.ec/http://revistasespam.espam.edu.ec/oai.Ecuador.1390-81031390-597Xopendoar:02025-02-25T14:32:02Revistas Escuela Superior Politécnica Agropecuaria de Manabí - Escuela Superior Politécnica Agropecuaria de Manabífalse |
