Agrosavia La 22: First variety of arracacha in Colombia
In Colombia, about seven regional materials are grown in monoculture and occasionally in associate, the cycle is annual and without planting seasonality, allowing harvesting throughout the year. Production is low with yields ranging from 7 to 13 t ha-1 and phytosanitary problems are presented in addition to the presence of commercial roots with unwanted purple pigmentations in the commercialization. In order to offer new genotypes, increase yields and meet the demand for yellow tuberous roots, the variety Agrosavia La 22 is obtained that preserves the color of the root and is the first genotype of this species to be registered in the national register of crops in Colombia. Agrosavia La 22 is the result of the selection of plants from sexual seed that were generated after the process of cross-pollination of accessions preserved in the germplasm bank in Colombia. Qualitative and quantitative descriptors of complete plant, leaf, seed, stem and tuberous root were used, as well as yield variables. After five evaluation cycles the results show that this variety has completely yellow roots, experimental yields of commercial roots of 33.48 t ha-1 and non-commercial of 1.31 t ha-1. On average a plant has nine commercial roots, each with an average weight of 271 g, 15 propagules per plant and tolerance to pests and diseases compared to commonly used genotypes.

En Colombia se cultivan alrededor de siete materiales regionales en monocultivo y ocasionalmente en asocio, el ciclo es anual y sin estacionalidad de siembra, lo que permite cosechar durante todo el año. La producción es baja con rendimientos que varían entre 7 y 13 t ha-1 y se presentan problemas fitosanitarios sumado a la presencia de raíces comerciales con pigmentaciones púrpuras no deseadas en la comercialización. Con el propósito de ofertar nuevos genotipos, incrementar los rendimientos y atender la demanda de raíces tuberosas amarillas, se obtiene la variedad Agrosavia La 22 que conserva el color de la raíz y es el primer genotipo de esta especie en ser inscrito en el registro nacional de cultivares en Colombia. Agrosavia La 22 es el resultado de la selección de plantas provenientes de semilla sexual que se generaron luego del proceso de polinización cruzada de accesiones conservadas en el banco de germoplasma en Colombia. Se utilizaron descriptores cualitativos y cuantitativos de planta completa, hoja, semilla, tallo y raíz tuberosa, además de variables de rendimiento. Luego de cinco ciclos de evaluación los resultados muestran que esta variedad tiene raíces completamente amarillas, rendimientos experimentales de raíces comerciales de 33.48 t ha-1 y no comerciales de 1.31 t ha-1. En promedio una planta tiene nueve raíces comerciales cada una con un peso promedio de 271 g, 15 propágulos por planta y tolerancia a plagas y enfermedades frente a los genotipos usualmente usados.
