Marlen

The Dutch Standard for Processing Industry

The 'Marlen' variety from the Agrico breeding house is a benchmark solution for growers focused on industrial processing. Developed by Dutch experts, this mid-late variety (growing season of 105–115 days) has firmly established itself in the french fry and potato chip production sector. With a high dry matter content (22–23%), it serves as a top-tier raw material, ensuring perfect texture and color for the final product.

Agronomic Profile and Protection

The core value of 'Marlen' lies in its comprehensive genetic resistance. Agrico Research has invested significant resources in building a shield against various threats that can deplete yields:

• Phytopathogens: strong immunity against potato wart disease and common scab.
• Viral Load: the variety shows high resistance to potato leaf roll virus and major potato viruses.
• Soil-borne Threats: high resistance to golden potato cyst nematode allows 'Marlen' to be grown in fields with a high infection pressure.

Despite its high productivity, the variety requires diligent adherence to best agricultural practices, particularly regarding late blight prevention, to which it shows moderate resistance.

Quality and Storage

Visually, 'Marlen' features classic round-oval tubers with yellow skin and deep yellow flesh. The tuber weight ranges from 50–130 grams, making it an optimal standard for automated sorting and processing lines. The variety is characterized by excellent storability, which is critical for enterprises planning to store produce to ensure continuous supply to processing plants throughout the season.
