DMS 3477

DMS 4377 (FAO 320)
High-Yield Dent Corn Hybrid with Excellent Stress Tolerance

DMS 4377 is a high-performing simple modified cross maize hybrid (FAO 320) developed for stable and profitable grain production across diverse growing conditions. With a yield potential of up to 19.2 t/ha, this hybrid combines outstanding productivity with excellent adaptation to drought and heat stress.

The hybrid produces attractive dent-type grain and well-filled ears with 16–18 kernel rows, ensuring high grain output and excellent marketability. Its Stay-Green characteristic allows plants to maintain green leaf area longer during grain filling, supporting efficient photosynthesis, improved stress tolerance, and greater yield stability.

DMS 4377 demonstrates excellent resistance to drought, high temperatures, head smut (Sporisorium reilianum), and European corn borer (Ostrinia nubilalis), while also showing very good tolerance to common smut (Ustilago maydis) and strong resistance to lodging. These traits make it a reliable choice for regions where environmental stress and disease pressure can limit productivity.

The hybrid also features:

• Excellent cold tolerance for reliable early establishment.
• Fast early-season growth and vigorous plant development.
• High grain drying rate, helping reduce drying costs at harvest.
• Medium-tall plant architecture with strong stalks and excellent standability.
