In the last century, more than a hundred of cultivars were used in the cotton production system in Colombia. Breeding for cultivars adapted to tropical environments had been the main purpose of the Colombian agricultural research institutions dedicated to cotton. Data describing yield and fiber quality traits of these cultivars (and the introduced ones mainly from USA) is scattered across grey literature which reduces chances of discovering, accessing and assessing this information.This data article contains databases describing i) Colombian and introduced Upland cotton cultivars used in Colombia and ii) ramulosis-resistance scores of lines developed by the Colombian breeding program. The first database was constructed from data extracted from grey literature mainly produced by ICA and CORPOICA (rebranded today as AGROSAVIA), the Colombian agricultural research agencies. The second one describes the Cereté lines (LCER) database. These advanced breeding lines were developed for improved yield performance in tropical environments, specifically monsoon and savanna climates. The LCER dataset also describes the ramulosis field resistance of these cultivars. Ramulosis is an endemic disease in South America caused by Colletotrichum gossypii var. cephalosporioides . The data in this article supports and augments information presented in the research articles [1]: and [3].

“…Para crear la escala se usaron los datos de densidad poblacional, donde la variedad en la cual el ácaro alcanzó las densidades poblacionales más altas en el ensayo de campo e invernadero se escogió para fijar el punto medio. El genotipo con los menores valores de densidad poblacional de T. leduni en la prueba de campo fue etiquetado como la variedad resistente de dicha escala (Moreno-Moran & Burbano-Figueroa, 2019).…”

Introducción. La berenjena Solanum melongena L. (Solanales: Solanaceae), es uno de los cultivos de hortalizas más importantes del Caribe Colombiano. Cultivo afectado por el ácaro rojo Tetranychus ludeni (Acari:Tetranychidae) el cual causa pérdidas económicas asociadas al rendimiento y contaminación ambiental por sobredosificaciones de acaricidas, lo que repercute en la salud de los agricultores y su familia. Objetivo. Evaluar la resistencia de siete materiales de berenjena a infestaciones artificiales de T. ludeni en condiciones de campo e invernadero. Materiales y métodos. El estudio se desarrolló entre abril y octubre de 2017 en el Centro de Investigación Turipaná de la Corporación Colombiana de Investigación Agropecuaria (AGROSAVIA). Los genotipos evaluados fueron las variedades Corpoica C029, Corpoica C015, las accesiones C036, C025, C049, y los cultivares regionales Buelvas y González; en campo e invernadero bajo un diseño en bloques completos al azar en tratamientos con cuatro repeticiones. Resultados. Las pruebas de campo mostraron diferencias significativas en la densidad poblacional de ácaros entre los materiales (F=4,42; p<0,0004), donde C025 tuvo los mayores valores y Buelvas los menores. La prueba de invernadero reveló diferencias en la densidad poblacional de ácaros entre materiales, con mayor población el cultivar C036 y con menor Buelvas. Conclusiones. Los cultivares regionales Buelvas y González exhibieron resistencia contra T. ludeni, proporcionando evidencia que existió resistencia a T. ludeni en campo en los materiales regionales de berenjena del Caribe colombiano. Las pruebas bajo invernadero, con las mayores densidades del ácaro, ofrecieron mayor poder discriminatorio y se sugieren en la fase inicial de evaluación completa del banco de germoplasma. Se sugiere el uso del cultivar Buelvas como genotipo resiste y C036 como genotipo de referencia susceptible a T. ludeni en futuros ensayos experimentales. Buelvas se recomienda como genotipo de referencia en razón de la estabilidad de la resistencia que mostró en campo e invernadero y asociada a mayores rendimientos.

Biotic stress in cotton plants caused by the phytopathogenic fungus Colletotrichum gossypii var. cephalosporioides triggers symptoms of ramulosis, a disease characterized by necrotic spots on young leaves, followed by death of the affected branch’s apical meristem, plant growth paralysis, and stimulation of lateral bud production. Severe cases of ramulosis can cause up to 85% yield losses in cotton plantations. Currently, this disease is controlled exclusively by using fungicides. However, few studies have focused on biological alternatives for mitigating the effects of contamination by C. gossypii var. cephalosporioides on cotton plants. Thus, the hypothesis raised is that endophytic fungi isolated from an Arecaceae species (Butia purpurascens), endemic to the Cerrado biome, have the potential to reduce physiological damage caused by ramulosis, decreasing its severity in these plants. This hypothesis was tested using plants grown from seeds contaminated with the pathogen and inoculated with strains of Gibberella moniliformis (BP10EF), Hamigera insecticola (BP33EF), Codinaeopsis sp. (BP328EF), G. moniliformis (BP335EF), and Aspergillus sp. (BP340EF). C. gossypii var. cephalosporioides is a leaf pathogen; thus, the evaluations were focused on leaf parameters: gas exchange, chlorophyll a fluorescence, and oxidative metabolism. The hypothesis that inoculation with endophytic strains can mitigate physiological and photochemical damage caused by ramulosis in cotton was confirmed, as the fungi improved plant growth and stomatal index and density, increased net photosynthetic rate (A) and carboxylation efficiency (A/Ci), and decreased photochemical stress (ABS/RC and DI0/RC) and oxidative stress by reducing enzyme activity (CAT, SOD, and APX) and the synthesis of malondialdehyde (MDA). Control plants developed leaves with a low adaxial stomatal index and density to reduce colonization of leaf tissues by C. gossypii var. cephalosporioides due to the absence of fungal antagonism. The Codinaeopsis sp. strain BP328EF can efficiently inhibit C. gossypii var. cephalosporioides in vitro (81.11% relative inhibition), improve gas exchange parameters, reduce photochemical stress of chlorophyll-a, and decrease lipid peroxidation in attacked leaves. Thus, BP328EF should be further evaluated for its potential effect as a biological alternative for enhancing the resistance of G. hirsutum plants and minimizing yield losses caused by C. gossypii var. cephalosporioides.
