The white grape variety is an interspecific new variety between Couderc 603 (Bourrisquou x Rupestris) x Couderc 906 (Emily x Jacquez). Synonyms are Couderc 146-51 and Pousse-Partout. Genes of Vitis aestivalis, Vitis labrusca, Vitis rupestris and Vitis vinifera are included. The hybrid was crossed in France by Georges Couderc (1850-1928). It is used as a wine grape and as a rootstock. No stocks were reported in 2016 (Kym Anderson).
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.
