Fifty potato genotypes from twenty-four different countries of origin, four different flesh colours (yellow, purple, red and marble) and different cultivation types (Andean accessions, landraces, breeder lines and cultivated varieties) were studied in terms of their nutritional and physicochemical characteristics. In general, cultivated varieties and breeder lines showed the highest similarity (slight differences only in some particular fatty acids distributions: C10:0, C12:0 and C22:0) concerning the physicochemical parameters assayed in this work, independently of the geographical origin or tuber flesh colour of these genotypes. Nonetheless, some of the studied landraces and Andean accessions proved to be similar enough to be considered as genotypes with good potential for commercial cultivation. These results can contribute to the supply of new potato genotypes into sustainable farming systems, supporting the protection of potato biodiversity, particularly Andean accessions, landraces and coloured genotypes (red or purple flesh) which are not widely cultivated so far.
本研究对来自二十四个不同国家、四种不同肉色（黄色、紫色、红色和大理石色）和不同栽培类型（安第斯品种、地方品种、育成品种和栽培品种）的五十种马铃薯基因型进行了营养和理化特性方面的研究。一般来说，不论这些基因型的地理起源或薯肉颜色如何，栽培品种和育成品种在本研究中测定的理化参数方面表现出最高的相似性（在某些特定脂肪酸分布方面仅有细微差异：C10:0、C12:0 和 C22:0）。然而，一些研究的地方品种和安第斯品种被证明足够相似，可以被认为是具有良好商业栽培潜力的基因型。这些结果有助于为可持续农业系统提供新的马铃薯基因型，支持对马铃薯生物多样性的保护，特别是迄今为止尚未广泛种植的安第斯品种、地方品种和有色基因型（红色或紫色肉）。
