Envisioned important advantage of participatory varietal selection (PVS) is increased adoption of improved cultivars due to speedy uptake by farmers. Conventionally adoption of improved cultivars is considered to have negative impact on biodiversity with declined the on-farm biodiversity. In contrast, participatory plant breeding techniques, including PVS, has been reported to increase biodiversity with some examples although increase process is not fully elucidated. As a part of International Rice Research Institute, Philippines and Institute of Agriculture and Animal Science, Nepal collaborative project, PVS was practiced in four villages of Sundar Bazaar, Lamjung, Nepal. Eight genotypes, (IR-55435-5, Ghaiya-2, Bindeshwori, Radha-32, B6149-MR-7, NR-1824-21-1-1, IR55539-2, Radha-4 ) five each for direct seeded and transplanted rainfed rice, along with local checks (Phakhe Jhinuwa and Gokule Mansuli) were grown in farmers' field in mother and baby trial design.
