F4987VO

Genetic architecture of the F4987VO hybrid

AF Flora's breeding strategy for the F4987VO model centers on building an 'immune barrier' that minimizes the need for heavy fungicide application. This simple sunflower hybrid maintains consistent vegetation cycles of 100–110 days, making it an optimal solution for temperate climate zones where quick return on investment during a tight agronomic window is critical.

Phytopathological resistance: core metrics

The crop's protection technology is based on comprehensive genetic resistance. The hybrid demonstrates high tolerance to the following pathogens:

• Fungal infections: White and Grey rot are blocked at early development stages due to high cell wall density.
• Oomycetes: Downy mildew (Peronospora) is neutralized by genetically integrated resistance factors.
• Leaf and stem infections: Phomopsis, Phoma, and Ascochyta — the F4987VO hybrid shows a significant reduction in infestation intensity, even under high disease pressure.

Morphology and oil content

A plant height of 170–180 cm ensures optimal mechanical harvesting, minimizing header losses. The medium-sized head is a selective feature designed to ensure high-quality grain filling even under moisture-deficit conditions. An oil content range of 50–55% positions this product as a high-profitability crop for oil extraction plants. The balanced leaf area index combined with moderate plant height allows for efficient photosynthetic resource allocation, directly impacting lipid accumulation in the kernel.
