Varietal Threat Index for Monitoring Crop Diversity on Farms in Five Agro-Ecological Regions in India

Our knowledge about the status of agrobiodiversity on farms is still very limited. While several studies to assess the crop genetic diversity on farms have been undertaken, there are no systematic documentation and monitoring practices for varietal diversity in space and time. Achievement of the agr...
