Potato Caruso

German Breeding for the Processing Industry

The «Karuso» variety by Solana embodies a pragmatic German approach to potato farming, focusing not on the aesthetics of table potatoes, but on high-performance processing metrics. The variety has established a solid niche as raw material for the production of chips and dried potatoes, driven by its genetic profile and crop stability.

Tuber Technological Profile

Karuso tubers are round-oval with a rough skin texture, which serves as an indicator of high dry matter content. With a tuber weight ranging from 130 to 200 grams, the variety provides excellent processing yields. The light yellow flesh, containing 18–19% starch, is ideal for deep processing: these tubers absorb less oil during frying and maintain structural integrity during dehydration.

Agronomic Resistance

Solana’s breeding program traditionally places significant emphasis on phytosanitary safety. Karuso demonstrates a comprehensive immune system that allows for reduced pesticide applications in the field. The variety shows high resistance to:

• Golden Potato Cyst Nematode (Ro1);
• Potato Wart;
• Common Scab.

Furthermore, the variety successfully withstands various other pathogens, including Rhizoctonia, blackleg, various types of tuber rot, and rust, which is crucial for obtaining high-quality raw material suitable for long-term storage. The growing period is 85–95 days, allowing producers to schedule harvesting in alignment with processing facility timelines.

For the farmer, Karuso is a tool for navigating a clearly segmented market. Due to medium-depth eyes and stable tuber size, the variety runs smoothly through automated washing and peeling lines, minimizing losses during the industrial preparation stage.
