There are at least four different grape varieties under these names. In 2016, however, no stocks were reported under this name (Kym Anderson statistics).
The white grape variety (also Manzoni 3.25) is a new cross between Regina (Afus Ali) x Lignan Blanc (Luglienga Bianca). The cross was made by the breeder Luigi Manzoni (1888-1968) in the mid-1920s at the viticultural institute in Conegliano (Veneto). The variety is used as table grape.
This white grape variety is a new cross between Italia x Queen of the Vineyards. The crossing was done by the private breeders M. Neagu and M. Georgescu in Romania. The variety is used as table grape.
There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
