Lettuce Kassandra

Italian Oak-leaf Lettuce for Commercial Production

The «Cassandra» lettuce variety from the Italian breeder Isi Sementi S.P.A is a professional-grade choice for growers focusing on the premium fresh greens market. Its primary value lies in the combination of a deep dark-red color and high resistance to pathogens, which effectively reduces the need for heavy fungicide application in both greenhouse and open-field environments.

Growing Scenarios and Management

In various cultivation conditions, «Cassandra» demonstrates consistent results throughout its medium-term maturity cycle. Being an "Oak-leaf" type, it develops a voluminous yet compact rosette, which significantly simplifies mechanized harvesting and minimizes leaf damage during post-harvest handling and logistics.

• Disease Resistance: Genetic resistance to downy mildew (Bremia lactucae) is critical for humid growing regions. Furthermore, the hybrid effectively resists powdery mildew and brown spot, preventing aesthetic degradation during the peak of the growing season.
• Continuous Production: Its predictable maturation timeline makes «Cassandra» an ideal component in a succession planting strategy, allowing producers to supply the market consistently without supply gaps.
• Logistical Advantages: The medium-sized, dense rosette handles storage well and retains turgor when proper temperature protocols are followed, making it an excellent candidate for salad mixes or whole-head retail sales.

This variety is highly recommended for spring and summer rotations, where the pressure from leaf-spotting diseases is typically higher. While «Cassandra» follows standard agronomic practices, it is particularly responsive to balanced nutrition, which is key to achieving its signature deep-red leaf coloration.
