A 105 R

Sustainable yields under heavy disease pressure

The A 105 R sunflower hybrid from the Novagrain Selection Center is engineered for farmers working in fields with high pathogen risks. This simple hybrid is built to offer robust protection against the complex of diseases commonly found in modern agricultural ecosystems, reducing the need for intensive fungicide usage.

Health and Immunity: A Shield Against Pathogens

The main advantage of A 105 R is its extensive natural resistance. It displays excellent tolerance to white and grey rot, downy mildew, phomopsis, and powdery mildew. Furthermore, it shows strong resistance to root rots and rust, ensuring the plant remains healthy from germination to maturity. This biological resilience makes it a reliable asset in regions where soil-borne diseases pose a constant threat to stand uniformity.

Agricultural Performance and Technology

A 105 R is fully compatible with the Clearfield (Euro-Lightning) production system, allowing for highly effective weed control and management of broomrape. With a vegetation period of 120–130 days, it fits well into mid-season harvest schedules. The hybrid delivers a competitive oil content of 45–50%, balancing productivity with consistent quality.

Morphology and Field Characteristics

With a plant height of 160–170 cm, A 105 R features large, well-filled heads. The sturdy stem structure minimizes lodging risks, even under variable weather conditions. This hybrid is ideal for intensive farming operations where farmers prioritize a combination of genetic protection and reliable response to herbicide application.
