Abstract Cacao (Theobroma cacao L.), the source of chocolate, is one most important commodity products worldwide that helps improve economic livelihood farmers. Diseases like frosty pod rot caused by Moniliophthora roreri and witches’ broom perniciosa limit productivity, this can be solved using resistant varieties. In current study, we sequenced 229 accessions genotyping-by-sequencing to examine genetic diversity population structure employing 9,003 8,131 single nucleotide polymorphisms...
A network of agronomists, researchers, and practitioners associated with cacao farming provided open access to their independent field trials across Latin America the Caribbean (LAC). centralized dataset was assembled using qualitative quantitative data from 25 experimental (hereafter referred as “CacaoFIT”) spanning several LAC agroecosystems. This used document main traits agroclimatic attributes cultivation model being tested within CacaoFIT network. By synthesizing an entire trials, this...
Frosty pod rot (FPR) disease on cocoa, caused by Moniliophthora roreri, is one of the most devastating cocoa in Western Hemisphere. In Colombia, particularly severe Magdalena Valley, which considered possible center origin for pathogen species. We analyzed genetic diversity isolates from departments Santander, Antioquia, Tolima, and Huila Colombia using 23 simple-sequence repeats (SSR) markers. total, 117 different multilocus genotypes were found among 120 isolates, each representing a...
The study was carried out in an agroforestry system (AFS) with cacao trees already established La Suiza Research Center, Corpoica, located Rionegro, Santander (Colombia). objective to evaluate biomass input and nutrient release rate of the species that comprise AFS (Gmelina arbórea, Gliricidia sepium, Cedrela odorata, Theobroma cacao). plant material decomposition process monitored bags after 8, 15, 23, 84 113 days, evaluating remnant weight nitrogen, phosphorous, potassium, calcium...
Frosty pod rot (FPR) caused by Moniliophthora roreri is the primary disease affecting cacao production in major producing countries of Americas and one threats to worldwide. The incidence FPR on clones with different levels resistance was investigated four localities Santander State, Colombia, between July 2013 May 2015. Dynamics diseased pods were modeled using boosted regression trees, a machine learning technique that allows regressions be performed without prior statistical assumptions....
Con el objetivo de introducir en la región del magdalena medio Colombia nuevos clones caucho (Hevea brasiliensis (Willd. ex A. Juss.) Müll. Arg.) alta productividad y con resistencia al Mal las Hojas, se evaluaron materiales un jardín clonal establecido Cimitarra, medio. Se evaluó incidencia severidad ataque Microcyclus ulei (P. Henn.) von Arx. según Garcia et al. (1). encontró completa mal hojas para los CDC 312, FDR 4575, 5597, 5788 MDF 180 parcial FX 3864 32. Los RRIM 901, PB 235 260...
Trees in cacao Agroforestry systems (AFS) may present a high potential for cadmium (Cd) phytoextraction, helping to reduce Cd (Theobroma L.) plants grown contaminated soils. To assess this potential, four forest fine-woody species commonly found high-productive sites Colombia (Tabebuia rosea, Terminalia superba, Albizia guachapele, and Cariniana pyriformis) were exposed contrasting CdCl2 contamination levels (0, 6, 12 ppm) on hydroponic medium. Growth dynamics, tolerance index (TI),...
The witches' broom (Moniliophthora perniciosa) is considered as one of the main threats for cacao production and, consequently, chocolate worldwide. In this work, genetic diversity and population structure M. perniciosa were analyzed 59 isolates collected in five departments Colombia using 10 microsatellite markers. Analyses revealed 35 multilocus genotypes clonal populations according to linkage disequilibrium analysis. One objectives study was determine whether differentiated by geographic...
The accumulation of high cadmium (Cd) levels in cacao beans (Theobroma cacao) generate several commercial and health issues. We hypothesized that phenotypic genotypic diversity could provide new insights to decrease Cd beans. Nine rootstock genotypes were evaluated for up 90 days under 0, 6, 12 (mg·kg−1) CdCl2 exposure content plant growth dynamics measured leaves, stems, roots. Data revealed all studied here highly tolerant Cd, since they presented tolerance index ≥ 60%. In shoots, EET61...
Las enfermedades foliares fúngicas son consideradas las principales causas del declive de la producción caucho natural en los países productores. Dada su importancia, el presente estudio se evaluó incidencia y severidad clones FX 3864, IAN 710, PB 217, 260, 235, 314, RRIC 110, RRIM 703, 600 establecidos campo clonal región magdalena medio santandereano. En cinco muestreos realizados entre agosto 2009 marzo 2010, determinó patógenos hojas estado B D, respectivamente. tejido foliar evaluados...
Los sistemas de sangría con estimulación se usan para minimizar costos y aumentar la producción látex. Por ello, evaluaron diferentes frecuencias sin EthrelÒ niveles fertilización en un cultivo del FX3864 Hevea brasiliensis 9 años edad Barrancabermeja, Santander. El estudio realizó diseño parcelas divididas distribuido bloques al azar, considerando como parcela principal los subparcela tratamientos dosis combinadas N, P K. La caucho seco, consumo corteza, incidencia seca fisiológica,...
Introducción. El ciclaje de nutrientes cumple un papel muy importante dentro la sostenibilidad sistemas productivos. En el cultivo cacao (Theobroma L.), descomposición biomasa generada por las podas es base fundamental en dinámica del sistema. Objetivo. Cuantificar tasa y liberación diferentes tipos residuos vegetales generados labores poda árbol cacao. Materiales métodos. estudio se realizó una finca cacaotera localizada Rionegro, Santander, Colombia, entre junio diciembre 2012. Se estimó...
Abstract Cocoa phytosanitary problems in Colombia are one of the main causes decline cocoa production, with losses that can reach 100% due to inadequate management. Ceratocystis wilt is a prevalent disease affecting crops country, C. fimbriata identified as its causal agent. However, there still inconsistencies at morphological level regarding species, which contradict relationship pathogen disease, diagnosis. Studies based on phenotypic and genotypic characterization species imperative for...
El cultivo de cacao en Colombia ha venido creciendo los últimos años y se consolida como un renglón la economía agrícola del país. Cada vez más requiere desarrollos tecnológicos que contribuyan a mejorar productividad rentabilidad. Una las causas bajo rendimiento es falta genotipos variedades productivas adaptadas seleccionadas para diferentes zonas con condiciones óptimas el cultivo. objetivo presente estudio fue evaluación agronómica ocho TCS13, TCS19 (Theobroma Corpoica La Suiza), SCC53,...
<p><strong>Background:</strong> In Colombia, most traditional cocoa crops are developed under agroforestry systems (SAF), associating shrubs and trees that provide shade for cocoa. They generate additional economic income various ecosystem services. <strong>Objective:</strong> To characterize with in three municipalities eastern Boyacá (Miraflores, Berbeo, Páez) belonging to the province of Lengupá. <strong>Methodology:</strong> A semi-structured...
