Sunflower N4H471 CL

Genetics and Clearfield Integration

The Nuseed H4X471 CL hybrid is a result of advanced breeding by Nuseed Europe, NuSeed Americas, and Jim Gerdes. This sunflower hybrid is specifically engineered for high-performance agriculture under heavy infection pressure. The core technological advantage is its full integration with the Clearfield (Euro-Lightning) system, allowing for clean weed management and effective broomrape control without compromising the crop’s physiological development.

Disease Defense Mechanisms

The hybrid’s breeding focus is heavily centered on building a robust phytosanitary barrier. It exhibits excellent resistance to Sclerotinia (white mold), Phomopsis, and Phoma. By limiting the susceptibility to stem and head rots, H4X471 CL provides a critical insurance policy against yield losses during the critical seed-filling stages when disease development often peaks.

Agronomic Profile

With a vegetation period of 100-110 days, this hybrid is designed to capitalize on early-season moisture while avoiding late-summer drought stress. The plant height (160-180 cm) ensures structural integrity and uniform development, facilitating efficient harvest operations. Furthermore, the oil content, consistently ranging between 45% and 55%, positions this hybrid as a high-value asset for oilseed processors, ensuring consistent profitability.
