Dataset for: Catalogue-Based Morphological and Agronomic Characterization of Native Potatoes in Paucartambo, Cusco, Peru

Through field evaluations conducted over two consecutive agricultural seasons, and in coordination with farmer custodians from localities such as Jailo, Cochachochayocc, Huancarani, and Totorani, among others, a total of 421 native potato varieties were characterised.

Morphological characterisation was carried out through participatory field sessions using standardised descriptors developed by the International Potato Center (CIP), assessing traits related to plant architecture, leaves, stems, flowering, pigmentation, fruiting, and tuber morphology. In addition, productive, physiological, and nutritional variables were recorded, together with qualitative information derived from local knowledge, including culinary uses, cooking time, perceived tolerance to climatic stresses, resistance to late blight, varietal category, perceived age, and perceived abundance.
