This document summarizes a presentation on monitoring genetic diversity of potatoes through in-situ conservation efforts. It discusses establishing baseline data through characterization of landraces across sites in potato diversity hotspots. Levels of monitoring include documenting total diversity, relative diversity through cultivar sampling, and spatial diversity through mapping field areas of different landraces. Threats to conservation and importance of collecting associated traditional knowledge are also covered. The goal is to create a global network for long-term monitoring of diversity changes over time in major roots, tubers and bananas through collaboration between farmers, researchers and organizations.
