| Sumario: | 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. |
