Sunflower MAS 95IR

The Genetic Architecture of MAC 95IR

French breeding from Maisadour Semences traditionally focuses on the balance between early maturity and intensive oil accumulation. The MAC 95IR hybrid is a simple sunflower hybrid engineered for stable performance in temperate climate conditions. With a vegetation period of 100 to 110 days, this genetic material allows farmers to optimize harvesting schedules, mitigating risks associated with prolonged autumn seasons.

Biological Defense: Phytosanitary Potential

The key feature of this hybrid lies in its genetically fixed resistance to a complex of pathogens that annually reduce yield potential in commercial fields. The engineered defense of MAC 95IR includes:

• Prevention of Verticillium wilt, a pathogen that affects the plant’s vascular system.
• Resistance to Sclerotinia (white mold), which is critical during high-humidity periods during flowering.
• Immunity to Phomopsis and Phoma, fungal diseases that damage stems and leaves, disrupting photosynthesis.

This resistance profile reduces the burden on fungicide application programs, allowing the plant to redirect energy toward head development rather than fighting off infection pressure.

Technological Quality Metrics

For processing plants, MAC 95IR serves as a reliable raw material. Oil content ranges from 45% to 50%, achieved through the plant's intensive metabolism during the seed-filling stage. The simple hybrid structure ensures crop uniformity, simplifying combine harvester adjustments and reducing harvest losses. This is a choice for growers seeking predictability within intensive cultivation systems.
