Variability, correlation, and path analysis in erect and prostrate cultivars of cowpea (Vigna unguiculata [L.] Walp.)

The cowpea bean (Vigna unguiculata [L.] Walp.) is the most important legume in the Colombian Caribbean, and is cultivated with genotypes having prostrate growth habit, with yields that do not exceed 700 kg ha-1. Manual harvesting is very expensive for crop rotation in commercial agriculture, which i...

description The cowpea bean (Vigna unguiculata [L.] Walp.) is the most important legume in the Colombian Caribbean, and is cultivated with genotypes having prostrate growth habit, with yields that do not exceed 700 kg ha-1. Manual harvesting is very expensive for crop rotation in commercial agriculture, which is why cultivars with erect growth habit are required. The research was carried out in the first semester of 2022, in the experimental area of the Universidad de Córdoba (Monteria-Colombia). Sixteen erect genotypes and five prostrate genotypes, including the control, were evaluated under a randomized complete block design with five repetitions. Each experimental unit consisted of two rows of 5 m in length, with a distance between plants of 0.15 m and between rows of 0.40 m for a population density of 166.000 plants/ha. The results indicated genetic variability, which enables successful phenotypic selection, according to the estimated genetic parameters. Likewise, there was positive and significant correlations of performance components with yield. In addition, the unfolding of genotypic correlations by means of path analysis indicated that grain thickness is an important and easy to measure characteristic to increase yield.

La cosecha manual resulta muy costosa para la rotación de cultivos en la agricultura empresarial, por lo que se requiere de cultivares de hábito de crecimiento erecto. La investigación se realizó en el primer semestre de 2022, en el área experimental de la Universidad de Córdoba (Montería-Colombia). Se evaluaron 16 genotipos erectos y cinco postrados incluido el testigo, bajo el diseño de bloques completos al azar con cinco repeticiones; cada unidad experimental estuvo conformada por dos surcos de 5 m de longitud, con distancia entre plantas de 0,15 m y entre surcos de 0,40 m para una densidad de población de 166.000 plantas/ha. Los resultados indicaron variabilidad genética, la cual posibilita la selección fenotípica exitosa, de acuerdo con los parámetros genéticos estimados. Así mismo, la existencia de correlaciones positivas y significativas de los componentes del rendimiento con el rendimiento. Además, el desdoblamiento de las correlaciones genotípicas mediante análisis de sendero indica que, el espesor del grano es una característica importante y fácil de medir para incrementar el rendimiento.application/pdfengengSociedad Colombiana de Ciencias Hortícolas-SCCH and Universidad Pedagógica y Tecnológica de Colombia-UPTChttps://revistas.uptc.edu.co/index.php/ciencias_horticolas/article/view/15508/12755Copyright (c) 2023 Revista Colombiana de Ciencias Hortícolashttp://creativecommons.org/licenses/by-nc-sa/4.0https://creativecommons.org/licenses/by-nc/4.0/http://purl.org/coar/access_right/c_abf552http://purl.org/coar/access_right/c_abf2Revista Colombiana de Ciencias Hortícolas; Vol. 17 No. 1 (2023); e15508Revista Colombiana de Ciencias Hortícolas; Vol. 17 Núm. 1 (2023); e15508Revista Colombiana de Ciencias Hortícolas; Vol. 17 No 1 (2023); e15508Revista Colombiana de Ciencias Hortícolas; V. 17 N. 1 (2023); e15508Revista Colombiana de Ciencias Hortícolas; v. 17 n. 1 (2023); e155082422-37192011-2173LegumesGrain qualityGenetic variabilityFood securityNutritional compositionBeansLeguminosasCalidad de granoVariabilidad genéticaSeguridad alimentariaComposición nutricionalFríjolesVariability, correlation, and path analysis in erect and prostrate cultivars of cowpea (Vigna unguiculata [L.] Walp.)Análisis de variabilidad, correlación y sendero en cultivares erectos y postrados de caupí (Vigna unguiculata [L.] Walp.)TextTextoinfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_7051http://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a635http://purl.org/coar/version/c_970fb48d4fbd8a85Colombia; Cordoba; MonteriaColombia; Córdoba; MonteríaAraméndiz-Tatis, HermesEspitia-Camacho, MiguelCardona-Ayala, Carlos001/17026oai:repositorio.uptc.edu.co:001/170262025-07-18 11:49:35.605https://creativecommons.org/licenses/by-nc/4.0/metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co
