In Peru there is a great diversity of native potatoes that differ by their sizes, shapes, skin and pulp colors, flavors and textures that they present. They are a source of micronutrients such as iron and zinc, which fulfill vital functions in the human body, and with which we can face food insecurity and child malnutrition. The aim of this research was to contribute to the study of 40 clones of biofortified native potatoes of potential use for the agroindustry from the germplasm bank of the Andenes Agrarian Experimental Station – INIA Cusco, through the morphological characterization and determination of the iron and zinc concentration. For this purpose, the Minimum Potato Descriptors (Solanum spp.) INIA manual was used, which allowed to identify great morphological variability. The characteristics that provided greater variability were stem color, secondary color of the flower, shape of the corolla, shape of the terminal leaflet, the color of the skin and pulp with its different distributions and the shape of the tuber with its variants; finding higher frequencies the blackish color of the skin, for the predominant and secondary color of the pulp the violet and white respectively and the oblong shape of the tuber. Likewise, through the wet digestion methodology and the atomic absorption spectroscopy technique,clones with a high concentration of iron and zinc were identify, being 183 mg.kg– 1 of Fe for clone 13 and 44 mg.kg–1 of Zn for clone 26 compared to other native cultivars and commercial potatoes. The highest yield was found in clone 23 and clone 29, with 22,9 t/ha for each.
