SR 1117 MK

Stable yields in challenging phytosanitary conditions

The French breeding of the CP 1117 MK hybrid by Lidea is an essential tool for farmers employing the Clearfield (Euro-Lightning) system. This sunflower is specifically designed for high field resistance to aggressive pathogens that often lead to premature crop failure.

Disease resistance as a primary advantage

A major concern for agricultural enterprises is crop infection by rot. CP 1117 MK demonstrates excellent tolerance to a range of diseases:

• Sclerotinia (white rot of the head and stalk);
• Phomopsis and Phoma;
• Grey rot.

This makes the hybrid a predictable choice for regions with high humidity or intensive farming schemes, where the risk of fungal infections is critically high. Using imidazolinone-based herbicides (Euro-Lightning) allows for effective control over the entire spectrum of weeds, including problematic varieties like broomrape, without concerns regarding crop phytotoxicity.

Agronomic Profile

The plants are characterized by a medium height of 170–180 cm, which simplifies harvesting and minimizes losses during combine operations. Under standard agricultural practices, CP 1117 MK shows consistent oil accumulation in the 45–50% range. The originator, Rustica Semences, has integrated potential into this hybrid that focuses on producing high-quality commercial grain suitable for oil extraction plants.

Practical Application

This hybrid is ideal for farms seeking a balance between security and yield performance. It is recommended for fields with high infection pressure where rigorous weed control via herbicide application is necessary. Its uniform height and resistance to rot simplify harvesting logistics, ensuring a well-filled head with high oil content.
