IR Lehat

High-Oleic Performance for Steppe and Forest-Steppe Zones

The "IR Legat" sunflower hybrid, a 2025 release from the V.Ya. Yuriev Plant Production Institute (NAAS of Ukraine), is designed for growers prioritizing early maturity combined with high-oleic oil content. This hybrid is specifically engineered to thrive in the challenging climatic conditions of the Steppe and Forest-Steppe regions, where moisture efficiency during the early vegetative stages is paramount.

Field Performance and Morphology

In the field, "IR Legat" displays robust development. Its medium plant height and strong root system provide excellent resistance to lodging. A notable morphological feature is the dense pubescence on the top of the stem, which acts as a protective barrier against heat stress and excessive moisture loss. The large, slightly convex head ensures uniform seed filling and simplifies the harvesting process.

Adaptability and Resilience

• Heat Tolerance: Its early maturity allows the crop to avoid peak heat stress during the critical grain-filling period.
• Morphological Defense: The flat leaf shape and moderate leaf size optimize transpiration, helping the plant maintain turgor even under soil moisture deficits.
• Agronomic Efficiency: The lack of branching and uniform flowering ensure consistent ripening, which is essential for efficient harvest planning.

"IR Legat" represents a strategic choice for modern farming. By combining the expertise of the Yuriev Institute with the specific needs of the high-oleic market, this hybrid offers a reliable solution for producers looking to balance yield stability with premium oil quality.
