TK 190

Genetic Resilience and Yield Potential of Woodstock TK 190

Hungarian breeding by Woodstock in the TK 190 model focuses on agronomic plasticity. This simple hybrid demonstrates exceptional adaptability across different climatic zones, largely due to its flint-dent kernel type. This grain structure optimizes the balance between high kernel test weight and efficient moisture loss during the maturation phase, facilitating timely harvesting.

Phytosanitary Defense System

The core advantage of TK 190 lies in its robust resistance to a complex of pathogens that threaten annual corn yields. Its immune profile is specifically engineered to mitigate the following threats:

• Stalk and root rots: The reinforced stem structure provides excellent standability, reducing lodging even in adverse weather conditions.
• Smut diseases (common and head smut): Genetic resistance minimizes losses during the grain-filling stage, ensuring consistent ear formation.
• Fusarium: Resistance to Fusarium infection ensures high-quality grain, crucial for both commercial use and high-grade silage production.

Furthermore, the hybrid exhibits significant resistance to the European corn borer. Physical barriers, such as tightly husked ears and specific plant tissue density, prevent major pest infestation, reducing the need for intensive chemical interventions.

Agronomic Management

The FAO range (90–1240) provides versatility, allowing for grain-focused or silage-focused management. The density flexibility—ranging from 60,000 to 90,000 plants per hectare—empowers agronomists to tailor seeding rates based on soil fertility and moisture profiles. In high-input scenarios with sufficient water availability, the higher density (up to 90,000 plants/ha) captures maximum yield potential per hectare. Conversely, the lower end of the spectrum (60,000 plants/ha) is ideal for risk-prone environments, ensuring that each plant has sufficient root space and access to limited soil nutrients to complete pollination successfully.
