Sunflower IMI AB 18

Technological potential of IMI AB 18

Serbian breeding by Institut Za Ratarstvo I Povrtarstvo (NS Seme) is traditionally focused on adaptability in challenging climatic conditions. The IMI AB 18 hybrid is a tool for intensive farming, where the key factor is weed control using the Clearfield (Euro-Lightning) technology.

Genetic foundation and resistance

The product is built on the extensive work of originators (Cvejic Sandra, Jocic Sinisa, etc.), aimed at creating a defense barrier against major sunflower pathogens. The practical value of the hybrid lies in its complex resistance to:

• Downy mildew (Peronospora): minimizes risks of stand density loss under high humidity.
• Phomopsis and Phoma: prevents premature stem desiccation, which is critical for maintaining head integrity until harvest.

Morphological features and productivity

The hybrid is of a simple type, ensuring high crop uniformity, which simplifies header adjustments and reduces losses during harvesting. Plant height of 170-180 cm is optimal for efficient photosynthesis at standard planting densities. A large head combined with high oil content (50-55%) allows for high yield performance even in fields with high herbicide load levels.

Why choose IMI AB 18?

The use of the Euro-Lightning system allows for the suppression of weed waves that compete with sunflowers for moisture and nutrients during critical growth phases. Combined with genetic disease resistance, this makes IMI AB 18 a predictable solution for farmers aiming to mitigate risks in unstable phytosanitary conditions.
