Whether it is taste, appearance, or disease resistance: many traits of our crop plants are defined in their genetic makeup. We research this genome to support the breeding of robust, high-quality varieties and to address practical questions regarding varietal authenticity.

Scope of Activities:

• Marker-assisted selection in apples: Using molecular markers, we evaluate young seedlings early on to identify plants carrying resistances (e.g., against apple scab) or desirable fruit quality traits. This makes the breeding process significantly more efficient.
• New Genomic Techniques (NGTs): We explore and apply innovative molecular biology methods in apple and grapevine to strengthen resistance and accelerate adaptation to climate change.
• Varietal and rootstock verification: Through DNA analysis, we reliably determine the identity and authenticity of varieties and rootstocks in apples and grapevines – for instance, to resolve ambiguities in commercial orchards, vineyards, or gardens.
• Genetic database: We are building a comprehensive database of DNA profiles for apple, grapevine, pear, cherry, and plum to uniquely identify varieties and safeguard genetic resources.
• Research on apple allergies: We investigate the allergenic potential of different apple varieties with the goal of developing and improving immunotherapy for birch pollen allergy through apple consumption.
