Lettuce CARTAGONOVA

Technical Profile of the Kartagonova Lettuce

The Kartagonova variety, developed by Monsanto, represents a high-performance butterhead lettuce cultivar designed for late-season production. From an agronomic standpoint, the value of this hybrid lies in its ability to maintain structural integrity and leaf quality under challenging late-harvest conditions where standard varieties often fail due to bolting or decline.

Genetic Resistance and Phytosanitary Resilience

Monsanto's breeding strategy for Kartagonova focuses on neutralizing major yield-limiting pathogens through integrated genetic resistance:

• Downy Mildew (Bremia lactucae): High level of resistance effectively reduces the reliance on fungicide spray programs, ensuring cleaner production cycles and safety for fresh-market distribution.
• Lettuce Mosaic Virus (LMV): Advanced resistance traits protect the crop from viral deformities, preventing growth stunting and ensuring uniformity in plant development and crop size.

Morphology and Marketability

Characterized by light-green leaves and a classic butterhead texture, Kartagonova provides the high visual quality demanded by modern retail standards. The average weight of the heads is optimized for efficient logistics and standardized packaging workflows. By focusing on late maturity, this hybrid allows growers to extend their production window, filling supply gaps when demand for high-quality greens is high but availability of premium-grade produce typically dwindles.
