The white grape variety is a new breeding between Chasselas x Muscat de Noir Eisenstadt (Ingram's Muscat). In your DNA analysis carried out in 2013, the parentage Muscat Noir du Jura (Muscat Noir) x Chasselas Violet given in the breeding list turned out to be wrong. However, this is based on only 20 DNA markers (see under molecular genetics). The cross was made in France in the 19th century by the breeder Henri Bouschet (1815-1881). The vine is used as a wine grape and table grape. No stocks were reported in 2016 (Kym Anderson statistics).
Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.
