Sunflower EH 500 SUL

Genetic Potential and Morphology of Hibrisol EX 500 SUL

The breeding partnership between Hibrisol S.L. and Apsov sementi S.p.A. has introduced the EX 500 SUL hybrid as a high-performance solution for intensive farming. The development focused heavily on plant architecture and physiological stress resilience. The 190–200 cm stem height ensures optimal biomass development, which, when paired with precise nutrient management, allows the plant to efficiently utilize soil potential for large seed filling.

Adaptability and Phytosanitary Protection

A major advantage of this hybrid is its resistance to pathogens that limit yield in high-humidity regions or areas with temperature fluctuations. Specifically, the hybrid's genetic profile includes mechanisms to block the development of rust and powdery mildew. This reduces the need for frequent fungicide applications and prevents premature senescence of the leaf canopy, which is essential for peak photosynthesis rates.

Head Characteristics and Yield Formation

The EX 500 SUL seed head features a slightly convex shape, an anatomically sound design that prevents moisture accumulation. The large head surface area, combined with large seed size, promotes higher oil extraction rates and excellent grain marketability. The dense seed arrangement minimizes the risk of hollow seeds often seen in other hybrids during drought, making this a reliable choice for consistent, high-volume harvesting.
