Description The data collection was implemented within the Chirapaq-Ñan initiative, a network for the long-term monitoring of in-situ conserved potato diversity in the light of socio-environmental changes. In its natural-sociocultural habitat, the potato continues to evolve, a process that facilitates the generation of new attributes required for the future and a "Darwinistic" adaptation to the processes of change. There are many varieties of potatoes that are only conserved in situ and not in gene banks. Basically, small farmers guard them. In situ conservation is part of the life strategies of small farmers because it is possible to diversify production, consumption, sales and social ties. The production of native potatoes has a high eco-geographic versatility. This versatility of the populations of native potatoes is an essential characteristic to face the climatic and environmental uncertainties, which characterize the high ecosystem of the Andes and to use the limited resources of the soil effectively through the sectorial system of land rest between 3,600 masl and 4,200 masl. There is a worldwide concern about the conservation of agrobiodiversity and its availability for future generations in the face of globalization and social-environmental changes. The documentation and establishment of a baseline of potato diversity in the Andean zone from the genetic / molecular level to the level of traditional / collective knowledge and spatial management of genetic resources in the communities is essential to reveal scientific evidence on the state of conservation of the total and relative diversity of the cultivated potato and the factors that determine its enrichment and / or loss. This dataset encompasses information of total potato diversity based on 30 critical morphological descriptors, collected on-farm in seven communities of the Peruvian Huancavelica diversity hotspot. Aspects of subterranaean and above-ground plant parts have been considered. Further, the ploidies of the landraces were determined by performing flow citometry.Morphological characterization and ploidy information of potato native varieties in-situ coserved at seven communities from Huancavelica hotspot.
