    • Identification of Farmers’ Preferred Varietiesthrough Participatory Variety SelectionApproaches in Western Hills of Nepal KB Koirala, YR Pandey, DB Gurung, SR Subedi and S Thapa
    • Introduction Maize is the most important crop in the hills of Nepal and ranks first in terms of area and production Maize contributes about 3.15% in national gross domestic product (GDP) and 9.5% in agricultural gross domestic product (AGDP) Maize occupies 40.6% area of the total crops in the hills
    •  It contributes 43.5% of total edible food production 70.23% of the total maize is grown in the hills Yield difference between improved and local maize is 687 kg/ha at the same level of management
    •  Out of the total maize area in the hills (614843 ha), 34.14% belongs to western hills with 2356 kg/ha productivity 86.77% maize is utilized for human consumption Opportunities have not been given to farmers to select varieties of their choices
    • Materials and Methods Varieties identified promising and newly released were tested in farmers’ fields to get feedback and identify farmers’ preferred varieties in different trials: I. Farmers field trials (FFT): 6-8 varieties, 6 rows of 3m long, 75cm x 25cm, N:P:K:120:60:40, 5-7 replications

    • Objectives Disseminating improved released and pipeline maize varieties in the western hills of Nepal Manakamana 5 focusing DAGs Identifying farmers’ preferred maize varieties through feedback given by the farmers on various traits Manakamana 6
    • Traits compared by the farmers (Household LevelQuestionnaires) Germination (1=better, 2=same, 3=worse) Plant height (1=shorter, 2=same, 3=taller)
    • Traits compared by the farmers Insect/pests problem (1=less, 2=same, 3=more) Lodging problem (1=less, 2=same, 3=more) Stay green character (1=stay green, 2=same, 3=dry) Maturity (1=early, 2=same, 3=late)• Grain yield (1=higher, 2=same, 3=lower)
    • Traits compared by the farmers Taste of roasted green cob (1=better, 2=same, 3=worse) Grit recovery (1=more, 2=same, 3=less) Taste of grits, bread, roasted grains (1=better, 2=same, 3=worse)
    • Identifying Farmers’ Preferences
    • Traits compared by the farmers Grain size (1=larger, 2=same, 3=smaller) Store grain pests (1=less, 2=same, 3=more) Finally, Focus group discussion is organized, 5-6 farmers in a group, Separate male and female groups to avoid mail dominance during discussion. Same questions as in HLQ

    • Conclusion Participatory variety selection is most effective for identification, promotion and dissemination of farmers’ preferred improved variety within a possible shortest period of time, and helps reach to unreached Majority of the farmers preferred Mana-3, Deuti, Mana 5, Mana 6 and Poshilo 1 for their higher yield, non-lodging, stay green character, bold grain size, acceptable colour and taste. Majority of the respondents have planned to plant these improved varieties in coming years too.
