Rete Semi Rurali is an Italian umbrella organisation, representing 35 national and regional organisations promoting Collective Management of Agrobiodiversity in organic and agroecological farming systems throughout the country. Founded in 2007, RSR has been actively promoting Participatory and Decentralised Plant Breeding for over ten years, through numerous Regional, National and European research projects. Starting from the conservation of local varieties and landraces, RSR is now researching and promoting the use of evolutionary populations of cereals, legumes and horticultural crops.
