LG 55.50

French breeding for stable yields

The LG 5550 hybrid from Limagrain is a prime example of high-tech European breeding, designed specifically for intensive sunflower production. Developed by French experts, this hybrid has established itself over years in the market as a reliable choice for farmers who prioritize the phytosanitary safety of their fields.

Biological defense and morphology

The key advantage of LG 5550 lies in its robust ability to withstand a wide range of pathogens. Reaching a height of 130–140 cm, the plant demonstrates excellent field resistance to diseases that often lead to significant yield losses:

• Root and stem rots: effective protection against charcoal rot and white root rot.
• Phomopsis and Phoma: strong field resistance to major fungal infections.
• Downy mildew: proven genetic resistance to common races.

Although the head of this hybrid is compact and small in size, this is balanced by a high seed filling density and superior grain quality. This morphology makes LG 5550 less susceptible to head rot, as moisture does not accumulate within the inflorescence, preventing mold development even under challenging weather conditions.

Why growers choose LG 5550

In today's market, where the risk of epiphytotics (mass disease outbreaks) is high, LG 5550 acts as an essential insurance policy for the crop. Its moderate growth habit simplifies the harvesting process and reduces equipment strain. This hybrid is perfectly suited for operations using traditional technology, where minimizing losses from pathogens without excessive fungicide costs is critical for profitability.
