| description |
Field experiments were conducted to evaluate agronomic traits and response to foliar fungal diseases of five advanced triple hybrids of hard yellow maize (Zea mays L.) and three commercial hybrids. An A × B factorial experiment with eight treatments, four repetitions and the Tukey test was used to compare means of the treatments (P>0.05). The most limiting disease is rust. The agronomic characteristics of breeding lines: h1, h2, h3, h4 and h5 (triple hybrids) were evaluated and compared with h6, h7, and h8 (commercial hybrids). Field trials were conducted in two locations of Central Coast of Ecuador (Quevedo & Balzar). Both locations showed significant differences for agronomic traits; Balzar presented lower yield (6,205.46 kg ha-1) and greater severity of curvularia leaf spot (3.34 CIMMYT scale) compared to Quevedo (7,368.21 kg ha-1 and 2.47 CIMMYT scale). For hybrids, h6 had significantly lower yield (5,306.83 kg ha-1), compared to h5 (6,914.09 kg ha-1), h1 (7,211.80 kg ha-1), h3 (7,266.83 kg ha-1), and h8 (8,036.85 kg ha-1). Significant differences were also detected for the orthogonal comparison (INIAP hybrids) with 5,634.44 kg ha-1 and the promissory lines with 6,997.68 kg ha-1. The highest net profit was achieved with the hybrid h2 with USD 1,405.76 followed by the hybrid h1 with USD 1,385,92, obtaining a Benefit-Cost ratio of 2.32 and 2.30 respectively, which indicates that for each monetary unit invested, an additional USD 1.32 and 1.30 of profit was obtained for the two hybrids, respectively. |

Se utilizó un experimento factorial A × B con ocho tratamientos, cuatro repeticiones y la prueba de Tukey para comparar las medias de los tratamientos (P>0.05). La enfermedad más limitante es la roya. Se evaluaron las características agronómicas de líneas mejoradas: h1, h2, h3, h4 y h5 (híbridos triples) y se compararon con h6, h7 y h8 (híbridos comerciales). Se realizaron experimentos en dos localidades de la costa central de Ecuador (Quevedo y Balzar). Ambas localidades mostraron diferencias significativas para las características agronómicas; Balzar presentó menor rendimiento (6.205,46 kg ha-1) y mayor severidad de la mancha foliar por curvularia (escala CIMMYT 3,34) en comparación con Quevedo (7.368,21 kg ha-1 y escala CIMMYT 2,47). Para los híbridos, h6 tuvo un rendimiento significativamente menor (5.306,83 kg ha-1), en comparación con h5 (6914,09 kg ha-1), h1 (7.211, 80 kg ha-1), h3 (7.266,83 kg ha-1), y h8 (8.036,85 kg ha-1). También se detectaron diferencias significativas para la comparación ortogonal (híbridos INIAP) con 5.634,44 kg ha-1 y las líneas promisorias con 6.997,68 kg ha-1. La mayor utilidad neta se logró con el híbrido h2 con USD 1.405,76 seguido del híbrido h1 con USD 1.385,92, obteniendo una relación Beneficio - Costo de 2,32 y 2,30 respectivamente, lo que indica que por cada unidad monetaria invertida USD 1,32 y 1,30 adicionales se obtuvo de ganancia para los dos híbridos, respectivamente.application/pdfengspaUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ciencia_agricultura/article/view/15544/13068Copyright (c) 2023 Ruth Angélica Cabascango-Paucar, William Mauricio Valverde-Pérez, Carlos Bolaños-Carriel, Julio César Basurto-Zambrano, Erwin Alexander García-Calderónhttp://creativecommons.org/licenses/by/4.0http://purl.org/coar/access_right/c_abf2Ciencia y Agricultura; Vol. 20 No. 1 (2023); 15544Ciencia y Agricultura; Vol. 20 Núm. 1 (2023); 155442539-0899Breeding plantYieldDisease resistanceNew cultivarsZea mays L.EcuadorMaiceMejoramiento de plantasRendimientoResistencia a enfermedadesNuevos cultivaresZea mays L.EcuadorMaízEvaluation of Agronomic Traits and Severity of Foliar Disease of Three Commercial Hybrids and Five Advanced Triple Hybrids of Hard Yellow MaizeEvaluación de características agronómicas y severidad de enfermedades foliares de tres híbridos comerciales y cinco híbridos triples avanzados de maíz amarillo duroinfo:eu-repo/semantics/articleTextTextohttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_2df8fbb1Ecuador; Quevedo y BalzarEcuador; Quevedo y BalzarCabascango-Paucar, Ruth AngélicaValverde-Pérez, William MauricioBolaños-Carriel, CarlosBasurto-Zambrano, Julio CésarGarcía-Calderón, Erwin Alexander001/10705oai:repositorio.uptc.edu.co:001/107052025-07-18 11:01:29.561metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co |
