The white grape variety is an interspecific new variety between Delaware x Chasselas Musque (Chasselas). Synonyms are Parker and Tucker's Parker. It contains genes from Vitis labrusca, Vitis aestivalis and Vitis vinifera. The hybrid was crossed in the USA in 1868 by the breeder Tucker. No stocks were reported in 2016 (Kym Anderson).
The wein.plus encyclopaedia is a comprehensive, well-researched reference work. Available anytime and anywhere, it has become an indispensable part of teaching, used by students and myself alike. Highly recommended!
