This document summarizes the story of participatory plant breeding and evolutionary plant breeding in Iran. It discusses how farmers in Iran are bringing biodiversity back to their fields by working with researchers to breed better crop varieties adapted to climate change. The process began with meetings between farmers and researchers to understand farmer needs and concerns regarding seeds and sovereignty. Farmers then evaluated 70 varieties of wheat and barley in their own fields, selecting the most resilient and adapted varieties. This participatory plant breeding approach is now being discussed more widely in universities and has led to the first PPB thesis being defended in Iran.
