Kerner (grape)

Intersection of Trollinger x Riesling

Kerner is a white grape variety. In their breeding at the remote location Lauffen the State Training and Research Institute for Viticulture and Pomology, which has its headquarters in Weinberg, 1929 red Trollinger and Riesling white were crossed by the Rebzüchter August Herold. The new variety was 1969 Plant Variety Protection and was entered in the same year in the list of varieties. At the beginning we talked about the white Herold, later was the variety with respect to the Swabian poet Justinus Kerner, who had lived in the vineyard, renamed Kerner. The details of the breeder to the crossing parents could be confirmed in the meantime by DNA analysis.

Kerner has gained importance in all German wine regions, especially fruity he is in Württemberg Heilbronn. Plantings are in the northern part of South Tyrol (Eisacktal - Valle Isarco ) to Brixen in Moravia ( growing area Znojmo ), Switzerland ( 18.5 acres, as of 2007, source: Federal Office for Agriculture BLW ) and in South Africa known.

1974, a mutation of the Kerner was found, the new varietal Kernling.

Ampelographic varietal characteristics

In the ampelography the habit is described as follows:

  • The shoot tip is hairy open and strong whitish.
  • The medium-sized leaves are indented five lobes and strong. The petiole is V-shaped or even overlapped. The blade is serrated to cut. The leaf surface (also called lamina ) is slightly blistered.
  • The shouldered grape is medium to large. The roundish berries are medium to large in size and of a greenish color. The shell of the berry is thick. The aroma of the berry is fine and has a weak varietal bouquet.

The Kerner drives from relatively late (shortly after the Müller -Thurgau ). Thus he escapes any late spring frosts. The flowering time is one to two days after the Müller- Thurgau. The Kerner makes a good winter hardiness. A disadvantage of the Kerner applies its susceptibility to disease, especially against powdery mildew. The vine tends to increased genetic avarice shoot formation. For this reason, the Kerner requires particularly careful care in the vineyards. In the case of infection with the transmitted by nematodes fanleaf disease of crop failure is stronger when compared with other varieties on the average. Very susceptible the variety reacts to an infection with the black spot ( Phomopsis )

Their wines similar to Riesling, have high sugar content, good acidity ( acid → (wine) ), sometimes a slight nutmeg. The variety is certainly one of the most valuable new varieties and bring to Silvaner sites produced very racy wines.

Kerner is a variety of the noble vine (Vitis vinifera ). It has hermaphrodite flowers and is thus self- fruiting. When the wine-growing economic disadvantage is avoided, no return delivered to have male plants grow.

Dissemination

In Germany 3848 hectares ( = 3.8 % of German vineyards ) were planted with the variety Kerner in 2007. In the year 2006 4004 hectares were planted after 6828 more acres were collected in 1999. He is successful in Rheinhessen ( 1,281 hectares in 2007), the Palatinate ( 1,164 hectares in 2007) and Württemberg cultivated (364 acres, 2006). The cultivation has declined drastically in recent years and suffers from the negative image as a new variety. By launched by the Laboratory vineyard " Justin K. " special line the value of this sort is to be deleted out. The label is subject to special requirements in the vineyard and cellar, and can be used nationwide.

Within Germany, the area under vines distributed as follows:
