Technical Specifications and Morphological Traits

The «Geyser» lettuce, developed by the Gavrish breeding firm, is a mid-season Batavian type variety. Originated through a collaboration between the Gavrish Breeding Firm, Dmitry Gladkov, and the Research Institute for Vegetable Crop Breeding, it is designed for consistent performance. With a maturation cycle of 45–55 days, it is well-suited for high-efficiency sequential planting schedules.

Key Advantages in Practical Cultivation

• Pathogen Resistance: The variety displays significant genetic resistance to powdery mildew, which helps minimize chemical inputs and lowers the risk of crop loss in both controlled and open-field environments.
• Physiological Tolerance: A standout feature is its resistance to marginal leaf necrosis. This trait is crucial for ensuring uniform quality, especially in conditions where temperature swings often lead to physiological breakdown in less resilient varieties.
• Product Characteristics: As a Batavian type, it forms a compact, medium-sized, dense rosette. The intense green coloration and resilient leaf texture ensure excellent post-harvest shelf life and ease of transportation, meeting retail requirements for fresh-cut greens.

For professional growers, the «Geyser» variety offers a stable yield with a high percentage of marketable output. Its resistance to common lettuce diseases and physiological defects reduces the labor costs associated with sorting and grading, providing a reliable economic return throughout the growing season.
