Dulcima

Engineering Potential of the Dulsima Hybrid

The Dulsima white cabbage hybrid by Rijk Zwaan is a high-performance genetic asset designed for professional vegetable farming with strict logistics and storage requirements. The core of this hybrid’s biological model lies in the balance between growth energy and internal structural density.

Head Architecture and Density

Technically, Dulsima was engineered as a versatile tool for both the fresh market and the processing industry. The rounded shape of the head ensures optimal mass distribution in the 2.0–5.0 kg range, which is the standard for mechanized harvesting and subsequent packaging. The density of the head is achieved through high dry matter content, which is critical for two key areas:

• Long-term Storage: The hybrid features excellent shelf-life and resistance to physiological defects when proper cold storage temperature regimes are maintained.
• Processing: The balanced chemical composition guarantees consistent quality for sauerkraut production and shredding, maintaining leaf integrity.

Agrotechnical Parameters and Adaptability

The biological development cycle (110–140 days) allows for flexible scheduling of planting and harvesting. The recommended planting density is 25,000–35,000 plants per hectare. This range is not merely a recommendation but a calculated parameter for forming high-quality marketable heads. At 25,000 plants/ha, the crop utilizes maximum resources for weight gain; at 35,000 plants/ha, the focus shifts toward smaller, denser heads suitable for retail distribution.

The green color of the leaves indicates high photosynthetic activity and efficient micronutrient uptake. Due to Rijk Zwaan’s breeding precision, Dulsima retains its commercial appearance even after prolonged transportation, minimizing losses when reaching fresh produce markets.
