Definition
Within the quality rice production in the Po Plain, Consorzio di Tutela e Valorizzazione delle Varietà Tipiche del Riso Italiano e delle Sue Tradizioni has recognized six "historical" varieties that are still widespread in the area. These varieties have been chosen for their agronomic and organoleptic features, as well as for their use in the preparation of traditional Italian dishes. These varieties belong to the subspecies Orhyza sativa japonica and are: Arborio, Baldo, Balilla, Carnaroli, Sant'Andrea, and Vialone Nano. The need to safeguard the historical varieties is highlighted by the fact that in 1971, year of their maximum development, they represented the 57.86% of the national rice production, while in 1998 they represented only the 31.36% of the total national production.
