Lemma

Technological features of Lema hybrid by Rijk Zwaan

In the ultra-early white cabbage segment, the choice of genetics determines not only the harvest date but also economic profitability. The Lema hybrid (Rijk Zwaan) is a balanced tool for obtaining marketable produce within a tight timeframe (40–50 days from transplanting). Dutch breeding here focuses on high head uniformity and adaptability to the stress factors of early spring.

Morphology and Marketability Management

The key task of the hybrid is to form a stable crop under unstable temperature conditions. The round-shaped head, weighing 1.0–2.0 kg, is an optimal standard for the fresh market, where portion-sized heads with dense internal structures are in demand. The lack of susceptibility to cracking, provided the irrigation schedule is followed, allows agronomists to vary harvest times without risking the loss of marketability.

Phytopathological Profile and Protection

Genetic resistance to a complex of pathogens is the basis for Lema's profitability. The manufacturer has paid special attention to protection against downy mildew. Using this hybrid significantly simplifies the fungicide application scheme, reducing the pesticide load during the early stages of vegetation. Resistance to powdery mildew and downy mildew is a critical factor when growing under cover or in protected ground, where air humidity often triggers the development of fungal infections.

• Ripening speed: 40-50 days, allowing for the fastest possible entry into the fresh produce market.
• Standardization: High head uniformity simplifies logistics and packaging.
• Market potential: An ideal balance between weight (1-2 kg) and head density.

By choosing Lema, the farmer gains a predictable result where the breeding advantages of Rijk Zwaan are backed by immunity to key diseases characteristic of the early growing period.
