SY HENRIETTA

Stable yields in challenging conditions

In the winter oilseed rape segment, Syngenta's "SI Henrietta" occupies a niche for farms prioritizing reliability and predictability. This simple linear hybrid from Swiss breeders provides a robust solution to the industry's demand for disease tolerance without compromising high productivity levels.

A Phytosanitary Barrier

The key competitive advantage of SI Henrietta lies in its strong resistance to Cylindrosporium leaf spot. In conditions of high humidity and sudden temperature changes, when pathogens can jeopardize a significant portion of the crop, this hybrid demonstrates remarkable resilience. It serves as more than just an insurance policy; it is a tool to optimize fungicide expenditure.

Growth Characteristics and Agronomy

The plants reach an optimal height of 160–170 cm. These parameters allow the hybrid to utilize its biomass effectively for seed filling while maintaining high lodging resistance. The potential yield of 40–50 c/ha is achieved by managing seeding density:

• Early sowing: 400,000 seeds/ha.
• Optimal sowing: 500,000 seeds/ha.
• Late sowing or unfavorable conditions: 600,000 seeds/ha.

Who is this choice for?

SI Henrietta is an ideal choice for producers facing challenges with fungal infections who aim to harvest high-quality commodity rapeseed consistently. The hybrid responds well to intensive cultivation practices and accommodates minor errors in density planning, ensuring uniform stand development and simultaneous maturation.
