Lettuce Dollar

Technical Potential of 'Dollar' Butterhead Lettuce

The selection product from the 'Sedek' agricultural company represents a classic butterhead lettuce (Lactuca sativa var. capitata). The primary technical objective addressed by the originators (Dubinin S.V., Dubinina I.N., Lukyanenko A.N.) was to balance vegetation speed with the formation of a dense, yet tender, inner head structure.

Morphological Features and Development

The plant belongs to the mid-season category, allowing for efficient conveyor-belt production planning. The butterhead type implies a specific leaf texture: it lacks the coarse fiber and bitterness characteristic of iceberg or certain leaf varieties. In practice, this means a high demand for a consistent irrigation regime; under moisture stress, butterhead varieties are prone to rapid accumulation of bitterness.

• Rosette Architecture: The average head weight ensures an optimal yield of marketable product per square meter. The leaf shape provides tight closure, protecting the inner parts of the plant from soil splash during irrigation and debris.
• Color Profile: A vibrant green hue is maintained until harvest, which is critical for visual appeal in retail environments.
• Agronomic Value: Performance stability is certified by the patent holder, 'Sedek'. The variety is adapted to regional climatic conditions, mitigating the risks associated with imported seed stock.

When cultivating 'Dollar', it is important to consider that butterhead varieties possess a more fragile leaf structure compared to crisphead types. This requires careful logistics and the avoidance of mechanical damage during harvesting and packaging. This variety is well-suited for the HoReCa and retail segments, which prioritize soft consistency and high organoleptic quality in greens.
