Local associations can play an important role in the sustainable management of agrobiodiversity. They are particularly relevant in marginal areas to improve crop productivity and facilitate income-generation. The Consorzio della Quarantina is one example resulting from the research and works of scholars since the mid-1980s. Initially, the focus of research work was on recovery of a white-fleshed potato variety (Quarantina bianca), traditionally grown in the mountains of Genova. The Consortium has 39 members, 23 of whom are farmers. Among these, 15 are producers of the Quarantina potato. In addition, the association has two affiliated shops that buy the potatoes directly from the Consortium; and nine collaborating farm guesthouses and ‘Bed & Breakfasts’. Recently, the focus shifted towards developing new varieties obtained from the cultivation of real seed of the Quarantina variety. This project, supported by the Liguria Region, aims at improving the productivity and resistance to Downy mildew of Quarantina potatoes. Comparative trials have been established at nine farms, mainly in the province of Genova; data are collected over a period of six years. This aspect is relevant because it demonstrates how conservation is linked to innovation and how synergies can be created between the perpetuation of tradition and modernity.
