| description |
The ostracism to which the species was subjected in the last century generated a weak use of genetic variability in the genetic improvement of characteristics of interest. This study aimed to estimate genetic parameters, correlation, and path analysis for 13 agronomic traits, cannabidiol (CBD) and tetrahydrocannabinol (THC) content in 10 cannabis genotypes from different departments of Colombia. The study was conducted under greenhouse conditions with a polycarbonate cover and anti-aphid mesh at the La Esperanza farm in Pueblo Bello, Cesar (North Colombia). A randomized complete block design with 10 treatments (genotypes) and three replicates was used. Each experimental unit consisted of 20 plants obtained from mother plants and transplanted at 14 cm between rows and between plants. Significant differences (P≤0.01) were detected between genotypes for all traits and THC and CBD content. Heritability in a broad sense showed values higher than 82% for all the traits studied. Genetic variability between genotypes was detected for number of leaflets, internode length of main stem, length of petiole, central leaflet-length, width of central leaflet, number of stems per plant, CBD, and THC, which allowed obtaining genetic gains higher than 30%. There was a high, inverse, and significant phenotypic and genotypic correlation between the percentage of CBD and THC (r=-0.93**). Overall, width of central leaflet direct and indirect effects explains the association level between CBD and THC with the correlated traits. It is possible to increase CBD and THC by selecting genotypes with higher width of central leaflet. |

El objetivo del estudio fue estimar los parámetros genéticos, correlación y análisis de sendero para 13 caracteres agronómicas, el contenido de cannabidiol (CBD) y tetrahidrocannabinol (THC) en 10 genotipos de cannabis procedentes de diferentes departamentos de Colombia. El estudio se realizó en invernadero con cubierta de policarbonato y malla antiáfido, en Pueblo Bello, Cesar (Colombia). Se utilizó un diseño de bloques completos al azar con 10 tratamientos (genotipos) y tres repeticiones. Cada unidad experimental estuvo conformada por 20 plantas obtenidas de plantas madre, y trasplantadas a 14 cm entre surcos y entre plantas. Se detectaron diferencias significativas (P≤0,01) entre genotipos para todas las características investigadas. La heredabilidad en sentido amplio acusó valores, superiores al 82% para todas las características. Se detectó variabilidad genética entre los genotipos para el número de foliolos, longitud de entrenudos del tallo principal, longitud del peciolo, longitud del foliolo central, anchura del foliolo central, número de tallos por planta, THC y CBD, lo cual permitió obtener ganancias genéticas superior al 30%. Existió correlación fenotípica y genotípica alta, inversa y significativa entre el porcentaje de CBD y THC (r=-0,93**). En general, el efecto directo e indirecto a través de la anchura del foliolo central explican el nivel de asociación entre CBD y THC con los caracteres correlacionados. Es posible aumentar el CBD y THC, a través de la selección de genotipos con mayor ancho del foliolo central.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/16862/13914Copyright (c) 2024 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_abf45http://purl.org/coar/access_right/c_abf2Revista Colombiana de Ciencias Hortícolas; Vol. 18 No. 1 (2024); e16862Revista Colombiana de Ciencias Hortícolas; Vol. 18 Núm. 1 (2024); e16862Revista Colombiana de Ciencias Hortícolas; Vol. 18 No 1 (2024); e16862Revista Colombiana de Ciencias Hortícolas; V. 18 N. 1 (2024); e16862Revista Colombiana de Ciencias Hortícolas; v. 18 n. 1 (2024); e168622422-37192011-2173CannabinoidsCorrelationsHeritabilityGenetic gainGenetic variabilityCannabisCannabinoidesCorrelacionesHeredabilidadGanancia genéticaVariabilidad genéticaCannabisGenetics parameters and path analysis in Cannabis sativa L.Parámetros genéticos y análisis de sendero en Cannabis sativa L.TextTextoinfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6544http://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a128http://purl.org/coar/version/c_970fb48d4fbd8a85Colombia; Cesar; Pueblo BelloColombia; Cesar; Pueblo BelloAraméndiz-Tatis, HermesCardona-Ayala, CarlosEspitia-Camacho, MiguelPastrana-Vargas, Iván001/17073oai:repositorio.uptc.edu.co:001/170732025-07-18 11:48:08.863https://creativecommons.org/licenses/by-nc/4.0/metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co |
