ABSTRACT

Lentil (Lens culinaris Medik.) landrace of Zaer had been on-farm conserved thanks to ingenious farmers' practices. Farmers had selected, produced and maintained their landrace to satisfy their food security, ecological and economical needs. However, the increase of drought incidence had encouraged farmers to gradual abandonment of their landrace for L56 improved variety to increase productivity and incomes. The landrace is therefore threatened for genetic drift by climatic change, varieties innovation and economic development. The main objective of this study is to strengthen the on farm conservation of lentil landrace of Zaer through its promotion under a distinctive sign of origin and quality in accordance with national agricultural policy. Thus, the investigation is focused on analyzing (i) farmers' knowledge through field survey of 41 farmers randomly chosen across Zaer region, (ii) genetic structure of landrace as meta-population and by four geographical locations using biochemical markers (SDS-PAGE), and (iii) genetic relationship between the landrace and L56 improved variety cultivated in Zaer. Data analysis had provide us with valuable information's on seed management according to climate and farmers' category, genetic structure of landrace as meta-population which was shaped by both natural pressures and human practices, and on seeds flow between landrace and L56 variety that might be linked to seed acquisition, spatial organization of production field or to post-harvest seed management.
