Most of seed production of sulla is restricted in specific areas of Central and Southern Italy: Tuscany, Abruzzo and Sicily regions. Sulla seed productions are obtained, above all, with not-certified seed of local varieties or ecotypes and 'commercial' seed without varietal certification. Certified seed production, in order to obtain 'basic' or 'certificated' seed of varieties registered on National Catalougue, is very limited (600 hectares). Seed production system is variable depending on the areas, climate and socio-economic aspects. The paper gives information concerning different cropping systems, seed rates and seed conditioning.
