OS 398

Technical Potential of the Saaten-Union OS 398 Hybrid

The breeding strategy of the OS 398 hybrid from the German company Saaten-Union focuses on the balance between early growth vigor and the capacity for efficient grain filling under variable temperature regimes. As a dent-type hybrid, OS 398 is engineered for rapid moisture release during the pre-harvest period, a critical factor in minimizing drying costs.

Phytosanitary Resilience as a Profitability Tool

The agronomic profile of OS 398 is built with a focus on comprehensive protection against pathogens that traditionally limit yields in high-humidity or intensive farming environments. Key protection indicators include:

• Helminthosporium and Fusarium: Advanced genetic selection has significantly reduced susceptibility to these fungal infections, preserving leaf integrity—a crucial factor for sustaining photosynthesis during the grain-filling stage.
• Stalk Rot: High resistance levels ensure plant structural integrity through harvest, eliminating lodging risks and yield loss.
• Common Smut: Inherent resistance minimizes the risk of abnormal growths on ears and stems, which is essential for high-quality commercial grain.

Practical Application in Crop Rotation

OS 398 exhibits high flexibility, making it a versatile choice for mixed-use operations. Due to its specific plant morphology, the hybrid delivers consistently high dry matter yields when harvested for silage, while maintaining excellent nutritional value. For grain production, the dent-type kernel structure ensures high test weight and efficiency during threshing. By utilizing OS 398, farmers can reduce fungicide applications throughout the growing season, relying on the built-in genetic resistance to key maize diseases.
