This paper summarises the findings of a research project on participatory plant breeding (PPB) in high altitude viilages of Chhornrong, Ghandruk, Lwang, Marangche, Siklis in Kaski and Bhujung in Larnjung districts of Nepal. The objective of the project was to monitor the spread of rice varieties from PPB in high altitude villages of Nepal. The villages have difficult physiographic terrain, poor accessibility, and weak institutional and infrastructural support. Spread of rice varieties was closely monitored by visiting the farmers in research villages. The study revealed that even in the lack of formal dissemination system, crop varieties can spread (some times to long distances) through personal contacts and farmers’ networks.
