Abstract:El propósito de esta revisión es ofrecer un documento comprensivo de los cultivares de algodón Upland introducidos en los sistemas de producción colombianos. En el caso de las variedades nacionales, toda la información referida a genealogía y características se encuentra dispersa en documentos de literatura gris, lo cual limita su hallazgo, acceso y evaluación. En este contexto, los objetivos de esta revisión fueron: i) describir las características y genealogía de las variedades de algodón Upland desarrollada… Show more
“…This collection was developed by the Instituto Colombiano Agropecuario (ICA) in the 1960s–70s and released them as commercial cultivars during the 1970s–80s. Some of these lines were used for the LC cotton breeding program [1].LC breeding lines (Líneas Cesar). These lines were created by CORPOICA in the 1990s using accessions of African origin developed by CIRAD, GS lines, STV115 and LC8590.…”

“…LC8590 is a Colombian accession without records about its origin. Seven commercial cultivars were released from this collection in the 2010s: Gaitana M109, Corpoica M123, Caribeña M129, Oro Blanco M151, Llanera M110, Vallenata M135, and Sinuana M137 [1].LCER breeding lines (Líneas Cereté).

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].

“…El programa de mejoramiento genético de Agrosavia en Colombia ha focalizado su objetivo en el desarrollo de variedades tipo Upland con adaptación en las regiones Caribe Húmedo, Caribe Seco y el Valle Cálido del Alto Magdalena (Burbano-Figueroa et al, 2018) y para adaptación específica a en la subregión 'altillanura plana', del cual se obtuvo Menegua, que además de tener adaptación a las condiciones de acidez, puede ser usada como cultivo de rotación en el sistema maíz-soya (Campuzano et al, 2015).…”
Menegua es la primera variedad de algodón específicamente para suelos ácidos en Colombia con recomendación, además de incluir en el sistema de rotación maíz-soya, como estrategia para ampliar la frontera algodonera en la subregión ‘altillanura plana’. No obstante, su manejo agronómico en relación con la distancia de siembra requiere de un ajuste como una estrategia para mejorar la competitividad del algodón en términos de rendimiento, calidad y costos. El objetivo de este estudio fue determinar el efecto del surco ultra-estrecho en comparación con el convencional en el desempeño productivo y calidad del algodón en condiciones de un suelo ácido oxisol en la altillanura plana colombiana. Se realizó un experimento en Puerto Gaitán-Meta, durante el ciclo agrícola 2015B, se usó un diseño de bloques completos al azar con dos tratamientos correspondientes a distancias entre surcos en cm): T1= 0.4 y T2= 0.8 y cuatro repeticiones; se utilizó la variedad Menegua con adaptación específica para suelos ácidos y se determinaron variables productivas y de calidad de fibra. El cambio de la distancia convencional de 80 cm a 40 cm ocasionó incremento de 13.1% en la altura de la planta, reducción 29.2% en el número de motas planta-1 y disminución 23.1% y 23.9% en el rendimiento de algodón semilla y rendimiento de algodón fibra, respectivamente, el porcentaje de extracción de fibra y su calidad no fue afectada. Se concluye que en la subregión ‘altillanura plana’ en un suelo ácido oxisol el surco ultra estrecho en comparación con el convencional afecto la variedad Menegua de manera negativa el comportamiento productivo sin detrimento de la calidad de la fibra en el algodón.
