EPrint Type:	Practice tool
Teaser:	The selection of new fungus-resistant grape varieties.
What problem does the tool address?:	Mildew fungi are one of the most dangerous vine diseases. Under favourable conditions, the course of the disease can reach epidemic proportions. Due to the infestation of flowers and grapes, there can be significant losses in yield lead to total harvest failure.
What solution does the tool offer?:	Innovative breeding methods were developed by the Swiss grape breeder Valentin Blattner. Every year he breeds thousands of new fungus-resistant grape varieties (PIWIs) that are specifically resistant to diseases such as powdery mildew (Oidium) and downy mildew (Peronospora). Valentin Blattner lets these new varieties grow in a test field without any plant protection in order to test their resistance. In autumn it becomes clear which plants have the necessary resistance genes and remain healthy, while others without these genes die.
