Maize Gran 310

The Mechanics of the Gran 310 Hybrid

Within the portfolio of VNIS, Gran 310 stands out as a triple-cross hybrid designed to optimize yield stability under varying environmental pressures. By moving away from simple single-cross structures, the breeders have created a hybrid with greater ecological plasticity. This architectural choice is intentional: it allows the crop to maintain metabolic efficiency during fluctuations in moisture and temperature, common in modern agricultural landscapes.

Core Technical Specifications

With a maturation cycle of 120–140 days, this hybrid falls into the medium-late maturity group, demanding precise management of thermal units. Key technical considerations include:

• Hybrid Architecture: The triple-line cross provides a robust heterotic effect, ensuring consistent field uniformity.
• Agronomic Density: The recommended stand density is 70,000–75,000 plants per hectare. Exceeding this threshold can trigger intra-specific competition, potentially compromising grain fill, while adhering to it maximizes the reproductive output.
• Versatility: Engineered for dual-purpose utility, Gran 310 performs equally well in grain production and high-quality silage management.

Field Performance and Plant Structure

The strength of Gran 310 lies in its stem integrity and root development. The breeding team at VNIS, led by the Parii family, has prioritized stalk strength to prevent lodging under intensive production systems. This is particularly relevant for growers applying heavy fertilizer loads. The hybrid balances significant biomass accumulation (essential for silage) with a high grain-to-cob ratio (essential for yield). By fostering rapid early-season growth, the crop effectively shades the ground, conserving soil moisture and creating a competitive edge against weed pressure. Gran 310 is a calculated choice for farms prioritizing agronomic reliability and versatility.
