“…A wide range of carbohydrates content (from 18.0 to 34.1 g/100 g on fresh weight) was found in the flesh samples, corresponding to energy values of 79.7-90.6% Kcal/100 g. The same trend was observed for the carbohydrates in the skin samples (from 18.3 to 33.3 g/100 g) with a contribution of 80.1-88.7% Kcal/100 g. These results were in some cases higher than those reported in the literature. Jimenez et al [12] studied 7 varieties of Andean potatoes and reported a carbohydrates content ranging from 12.6 to 22.6 g/100 g fresh weight; analogously, Calliope et al [8] showed values from 11.9 to 24.0 g/100 g, analyzing 44 different genotypes of Andean potatoes. According to these and other authors [2,8], the observed variability might be due to genotype, reported as one of the most significant factors affecting the nutritional characteristics of different crops.…”

“…Andean genotypes show the widest biodiversity in tuber shape, flesh and skin color, texture, and flavor, and this might lead to a considerable variability in nutritional and bioactive compound contents, as highlighted in several studies [5][6][7][8].…”

The characterization of six varieties of native Andean potatoes with a wide biodiversity in tuber shape, flesh, and skin color was performed, through the determination of their proximate composition, mineral content, and phenolic profile. Minerals concentration revealed significant genotypic variation. Potassium was the most abundant element in all varieties, ranging from 7272.9 to 13,059.9 µg/g and from 12,418 to 17,388.6 µg/g dried weight for the flesh and skin samples, respectively. Iron content was relevant, ranging from 20.5 to 39.9 µg/g and from 112.2 to 288.8 µg/g dried weight in flesh and skin samples, respectively. Phenolic compounds were consistently higher in the skin than in the flesh. The total content varied greatly from 19.5 to 2015.3 µg/g and from 1592.3 to 14807.3 µg/g dried weight for flesh and skin tissues, respectively. 5-caffeoylquinic acid was 74% of the total phenolic acids. Different pattern of anthocyanins was found, depending on the color of the variety; the red genotypes contained predominantly pelargonidin derivatives, while the purple samples had petunidin as a major anthocyanidin. This study increases the knowledge of the composition of the local Andean varieties (which are only scarcely studied so far), helping to enhance these genotypes and the conservation of biodiversity.

“…There is growing interest in the study and conservation of these potato varieties for many reasons, including: to understand of their evolutionary process in a certain region [5], to contribute to the conservation of biodiversity and reduction of the loss of genetic diversity in native or introduced varieties [6], to generate technological innovations in production and post-harvest, to introduce them in value chains and fortify producers [7], to increase the visibility of native potatoes, and highlight their characteristics to promote greater consumption [8,9].…”

Las variedades nativas presentan la oportunidad para recuperar la biodiversidad y contribuir a la seguridad alimentaria en algunas regiones de bajo desarrollo, sin embargo no han sido estudiadas lo suficiente. Se someten a diferentes temperaturas de almacenamiento las variedades de papa nativa Curiquinga y Ratona Morada cultivadas en el departamento de Nariño para observar el comportamiento de característicascomo humedad, pérdida de peso, contenido de glucosa y ácido ascórbico. La variedad Ratona Morada conserva mejor sus características en refrigeración, deteriorándose más rápido en incubación, la Curiquinga en cambio presenta mayor deterioro en refrigeración que en temperatura ambiente e incubación. Se recomienda profundizar los estudios de almacenamiento pos cosecha en variedades nativas para enlazar la producción con el procesamiento que permita generar cadenas agroindustriales de valor agregado, conservar estos recursos genéticos y brindar alternativas a pequeños productores.

“…La caracterización morfológica de los tubérculos puede considerarse como fuente de información para identificar genotipos en los bancos de germoplasma (Calliope et al 2018). Madroñero et al (2013) señalan que las mejores variables para la caracterización son aquellas relacionadas con el color de tallo, color de brote y color y forma de baya.…”

En este presente trabajo, la diversidad genética de 30 morfotipos de papas nativas de Vilcashuamán (Ayacucho) fue evaluada mediante la técnica de polimorfismo de longitud de fragmentos amplificados (AFLP). La extracción de ADN se realizó con el método de CTAB modificado, usando hojas frescas de plantas de cuatro semanas de cultivo en invernadero. Partiendo de 200 mg de tejido vegetal se logró obtener entre 300 a 500 ng/μL de ADN de buena calidad. La digestión enzimática del ADN se realizó utilizando EcoRI y MseI, y se emplearon 12 combinaciones de primers, de las cuales se eligieron las dos combinaciones más polimórficas (E13 – M49 y E38 – M49). El análisis estadístico se realizó con el programa NTSYs 2.10 usando el coeficiente de Simple Matching logrando obtener valores de PIC (índice de contenido polimórfico) de 0.45 y 0.40 para las combinaciones E38 – M49 y E13 – M49, respectivamente. En total se lograron identificar 68 bandas claramente diferenciables, de las cuales el 55.8% fueron bandas polimórficas. El análisis de agrupamiento según el algoritmo UPGMA originó un dendograma con un índice de correlación cofenética de r= 0.7; a un coeficiente de similitud de 0.6; se establecieron ocho grupos genéticos y a un coeficiente de 1 no se encontraron morfotipos duplicados. Los resultados obtenidos demuestran el alto poder informativo del AFLP y la alta variabilidad de las papas nativas estudiadas.
