The red grape variety originates from France. Synonyms are Rouge de Diolly, Salagnin and Sasteigne. It was once cultivated in the Département Drôme in the Rhône valley and was considered extinct. In the 1920s, the vine was discovered by the Swiss vine breeder Dr Henri Wuilloud near the municipality of Diolly in the canton of Valais and was first named Rouge de Diolly after the place where it was found. According to DNA analyses carried out in 2013, it is a presumably natural cross between the varieties Mondeuse Blanche (white) x Tressot Noir (red). However, this is based on only 20 DNA markers (see molecular genetics). Robin Noir was a crossing partner in the new variety Diolinoir. No stocks were reported in 2016 (statistics Kym Anderson).
