Summary: Maize (Zea mays) productivity in the middle hills of Nepal has been either static or declining in the last two decades. Attempts to reverse declining yields through participatory variety selection (PVS) and participatory plant breeding (PPB) were investigated at three sites in the eastern middle hills of Nepal, each with 27 participating farmers for two consecutive years (1999 and 2000). Four composites were generated through PPB with different crossing combinations of exotic varieties with the most adapted local germplasm as indicated by farmers. Maize varieties Manakamana-1, Arun-1, BA-93-2126#2, Population-22, and two local composites were compared with locals in farmer-managed participatory research trials and varietal demonstration trials. PQpulation-22, despite its late maturity, was liked by farmers because of disease tolerance, yield potential, large white grains and its "stay green" characteristics. Statistical analysis of grain yield confirmed farmers' preference for Population-22, since this out-yielded other varieties. Arun-1 was the lowest yielder; however farmers were adopting it because of the early food availability conferred by its short duration.
