The white grape variety is a new breeding between Schiava Grossa (Trollinger) x Riesling, which was most recently confirmed by DNA analyses carried out in 2018. Synonyms are Herold Triumpf, Kerner Bijeli, Kernerrebe, Trollinger x Riesling Renano S 25/30, Weinsberg S 25 and (first name) Weißer Herold. The cross was made in 1929 at the Staatliche Lehr- und Versuchsanstalt in Weinsberg (Württemberg) by the breeder August Herold (1902-1973). Plant variety protection was granted in 1969. The name was given after the Swabian doctor and wine writer Justinus Kerner (1786-1862), who lived in Weinsberg. Incidentally, the same parents also gave rise to Rotberger and Witberger. Kerner was a crossing partner of the new varieties Juwel, Roter Milan and Silcher. One mutation is Kernling, which is characterised by fewer stingy shoots.
