How much does the proportion of areas on which fungus-resistant grape varieties are cultivated grow when comparing varieties and regions? Board members of the PIWI Germany association determined the data.

A selection of white and red PIWI grape varieties was examined in more detail in several articles that appeared in the specialist magazine der deutsche weinbau. This included, among other things, the characteristics of the individual grape varieties, resistance, information on suitability for cultivation and the origin of the crosses. The following article focuses on the development of vineyard areas planted with PIWIs in Germany. White:

Cabernet Blanc, Souvignier Gris, Sauvignac, Muscaris, Sauvitage, Calardis Blanc, Hibernal and Saphira. Red: Regent, Cabernet Cortis, Pinotin, Satin Noir, Cabertin, Prior and We 94-26-37. The grape varieties were bred by different research institutes or vine breeders and showed varying levels of resistance to oidium, downy mildew, botrytis, cherry vinegar fly, stem rot and frost.

NOTE: UNFORTUNATELY, THERE IS AN ERROR IN THE DATA, ESPECIALLY FROM 2022. THE AUTHORS ARE WORKING ON CORRECTING THE PUBLISHED DATA.
