Managing on farm populations. Mixtures of landraces or old varieties (Liveseed Practice Abstract)

Practical recommendations: Selection will be continuously applied by the farmer since the environment/practices will make evolve the populations; he will observe his field and determine the best part for seed production. Local (collective or individual) technological means should be available for seed preparation (sorting and calibration) and conservation. Create market for dynamic and heterogeneous populations if needed and cooperate with local organisations/food chains
