ZUZANNA

Genetic Potential and Immune Architecture

The “Susanna” potato variety from the German breeding company Europlant Pflanzenzucht is a high-tech product aimed at the premium table potato market. The main technical feature of this variety is its high starch content (21-22%), positioning it among the most sought-after varieties for both processing and culinary use. The high dry matter content ensures an excellent texture, as the tubers retain their shape during cooking.

Phytosanitary Resistance as a Cost-Reduction Tool

Europlant breeders have integrated a comprehensive defense system into the Susanna genome, significantly reducing the need for chemical crop protection:

• Nematode Resistance: High resistance to the golden potato cyst nematode (Globodera rostochiensis) allows for cultivation in tired soils without the risk of yield loss.
• Pathogen Barrier: The variety shows exceptional resistance to potato leafroll virus. This is critical for maintaining canopy photosynthetic activity during the final stages of vegetation.
• Disease Resistance: Genetic defense against blackleg and common scab ensures a marketable yield with clean, smooth skin, a key factor for retail distribution.
• Late Blight Tolerance: Robust resistance to late blight minimizes the risk of infection spread during periods of high humidity.

Morphological and Market Specifications

Visually, Susanna meets rigorous market standards. The oval-to-round shape of the tubers is ideal for automated washing, sorting, and packaging. The light yellow (almost white) skin combined with matching flesh color gives the product a high-quality aesthetic appeal. The technical performance of this variety allows agronomists to project stable marketable yields under standard agricultural protocols.
