Z & Endl) H. Robinson is an Asteraceae native to the Andean region. It is a plant used by antiquated cul­tures as a refreshing fruit or low calorie food. Its roots are composed mostly of water (85-90%). 40 to 70% of its dry weight comes in the form of fructooligosaccharides (FOS), sugars with favo­rable effects on human health, and with a high antioxidant power, which is why it is considered medicinal; for the treatment of problems associated with diabetes. The high demand and price of the product in the domestic and international markets make this species a profitable option for farmers in the Eje Cafetero (Colombian Coffee) ecoregion, which has ideal agro-ecological con­ditions for its cultivation. However, there is neither precise information on the materials present in the region nor information on its productivity, making it difficult to propose the appropiate agrono­mic management to optimize its production. This research was conducted in five provinces of the Eje Cafetero ecoregion, collecting and morpho­logically characterizing the species. Subsequent morphoagronomic evaluations were performed using 18 quantitative descriptors, and eight qua­litative ones, in addition to the molecular characterization with the RAMs technique using six initiators. The morphoagronomic characterization classified the ten collected biotypes into three groups. Molecular characterization distinguished four groups, which are closely related to the grou­ping according to the qualitative characteristics found. The paper concludes that the accessions of group one are the most appropriate for the production of tubers, those of group two for dual-purpose production and those of group three, for leaf production. The multiple correspondence analysis (MCA) indicates that within the germplasm there are important characters that can be used towards the selection of potential parents with desirable quality traits for breeders, farmers and consumers.

El 40 al 70% de su peso seco está en forma de frutooligosacáridos (FOS), azúcares con efectos favorables para la salud humana, y con un alto poder antioxidante, por lo que es considerado como medicinal, para tratar problemas de diabetes. La alta demanda y precio del producto en el mercado nacional e internacional hacen de ésta especie una opción rentable para los agricultores de la ecorregión Eje Cafetero, que cuenta con las condiciones agroecológicas ideales para su cultivo. Sin embargo, no se conoce información precisa sobre los materiales presentes en la región, ni de sus rendimientos, lo que dificulta proponer un manejo agronómico adecuado, para optimizar su producción. Esta investigación se realizó en cinco departamentos de la ecorregión Eje Cafetero, colectando y caracterizando morfológicamente la especie. Posteriormente se realizaron evaluaciones morfoagronómicos empleando 18 descriptores cuantitativos y ocho cualitativos, y caracterización molecular con la técnica RAMs, utilizando seis iniciadores. La caracterización morfoagronómica clasificó los diez biotipos colectados en tres grupos. La caracterización molecular diferenció cuatro grupos, que guardan estrecha relación con el agrupamiento según los caracteres cualitativos encontrados. Se concluye que las accesiones del grupo uno, son las más apropiadas para la producción de tubérculos, las del grupo dos, para la producción doble propósito y el grupo tres, para la producción de hojas.

The high demand and price of the product in the domestic and international markets make this species a profitable option for farmers in the Eje Cafetero (Colombian Coffee) ecoregion, which has ideal agro-ecological con­ditions for its cultivation. However, there is neither precise information on the materials present in the region nor information on its productivity, making it difficult to propose the appropiate agrono­mic management to optimize its production.

    O yacon (Smallanthus sonchifolius Poep. Z e Endl) H. Robinsón, é uma Asteraceae originaria da região andina. É uma planta utilizada pelas culturas antepassadas como uma fruta refrescante e alimento de baixa caloria. Suas raízes estão compostas em sua maioridade por água (85 a 90%). O 40 a 70% de sua matéria seca estão em forma de frutos oligosacaridios (FOS), açucares com efeitos favoráveis para a saúde humana, e com um alto poder antioxidante, por isso é considerado uma planta medicinal, para tratar problemas de diabetes. A alta demanda e preço do produto no mercado nacional e internacional fazem da espécie uma opção rentável para os agricultores da ecoregião do “Eje cafetero” que contam com as condições agroecológicas ideias para o seu cultivo. Contudo, não se tem conhecimento sobre a aérea cultivada na região, nem de seus rendimentos agrícolas, o que dificulta propor um manejo agronômico adequado para otimizar sua produção. Esta investigação foi realizada em 5 municípios da ecoregião do “Eje cafetero”, coletando e caracterizando morfologicamente a espécie. Posteriormente se realizaram avaliações morfoagronômicas utilizando 18 descrições qualitativas e quantitativas e caracterizações moleculares com a técnica de RAMs, utilizando seis indicadores. A caracterização morfoagronômica classificou os dez biótipos coletados nos três grupos. A caracterização molecular diferenciou quatro grupos, que guardam uma estreita relação com o agrupamento segundo as carac­terísticas qualitativas encontradas. Concluiu-se que as seções do grupo 1 são as mais apropriadas para a produção de tubérculos. As do grupo 2, para a produção dupla e o grupo 3 para a produção de folhas. A análise de correspondência múltipla indica que no germosplasma existem características importantes, que podem servir para a seção de possíveis genes parentais com características qualitativas desejáveis para criadores, agricultores e consumidores.
