Dataset for: Temporal Dynamics of Potato landraces diversity in Paucartambo, Cusco

The historical native potato database includes records from 1927 to 2020 and was expanded with additional information collected in 2022, reaching a total of 15,257 observations. It also incorporates data from 335 farming families surveyed in 2022. The names of the landraces were previously standardized to ensure consistency across all sources.
