The white grape variety originates from Italy. The name derives from the golden yellow berries (d'oro). Synonyms are Doro di Venezia, Dorona, Dorona Veneziana, Fedit 51, Fedit 51-C, Fedit 51 C.S.G., Incrocio Bianco Fedit 51 (second main name), Incrocio Bianco Fedit 51 C.S.G., Incrocio Fedit 51 and Uva d'Oro. Some synonyms (Fedit 51 etc.) and a confusing breeding list entry indicate that the variety was newly b red in 1951 (apparently an unknown breeder falsely declared the already existing variety as his breeding success). However, according to DNA analyses carried out in 2013, it originates from a presumably natural cross between Bermestia Bianca x Garganega. According to one hypothesis, it was already known in the 15th century, but this probably refers to the frequent confusion with the Garganega variety, to which this applies. The medium to late ripening vine is resistant to botrytis and drought. It is well suited for the production of passito (sweet wine) and is also used as table grape. The variety is cultivated in the Veneto region in the provinces of Vicenza and Padua. It is no longer important; in 2016, only one hectare of vines was reported under the name Incrocio Bianco Fedit 51, with a downward trend (Kym Anderson statistics).
