Andean potatoes (Solanum tuberosum andigenum) are a staple food for Andean population; there is great biodiversity but only few varieties are cultivated nowadays. In order to contribute to biodiversity conservation of Andean potatoes, information about their morphological, nutritional and functional characteristics was generated. In gene bank (INTA-Balcarce), varieties collected from regional producers were preserved. Forty-four genotypes were multiplied and characterized. Morphological characteristics; proximate composition and functional compounds were analyzed. Cluster analysis separated them into 3 groups according to distinguishing characteristics, which define industrial or nutritional applications. Group 2 was characterized by higher content of macronutrients and Group 3 with the highest antioxidant activity, both would be advisable for direct consumption. Genotype CS 1418 had big size and oval form so it could be destined to potato chips industry. Knowledge on nutritional and functional properties of genotypes contributes to promoting the cultivation depending on properties and also to preserve biodiversity.
安第斯土豆（Solanum tuberosum andigenum）是安第斯地区居民的主食；其生物多样性丰富，但如今仅有少数品种得到种植。为助力安第斯土豆的生物多样性保护，已生成了有关其形态、营养和功能特性的信息。在基因库（INTA - 巴尔卡斯）中，保存了从当地生产者处收集的品种。对44种基因型进行了繁殖和特性鉴定。分析了形态特征、近似成分和功能化合物。聚类分析根据区分特征将它们分为3组，这些特征决定了其工业或营养用途。第2组的特点是大量营养素含量较高，第3组具有最高的抗氧化活性，这两组都适合直接食用。基因型CS 1418个头大且呈椭圆形，因此可用于薯片产业。了解基因型的营养和功能特性有助于根据其特性推动种植，并保护生物多样性。
