Rayma RZ F1

Agronomic Profile of Reyma RZ F1

The Reyma RZ F1 hybrid by Rijk Zwaan is an intensive-type white cabbage variety engineered for early-season production. The breeding focus for this hybrid was to overcome critical early-vegetable cultivation challenges, such as short daylight hours and fluctuating spring temperatures, ensuring stable yield performance.

Vegetative Balance and Marketability

With a maturation period of 50–60 days, this hybrid is designed for early-market entry. It develops dense, compact heads weighing 1.0–2.0 kg. The rounded shape and distinctive grey-green leaf color offer strong visual appeal for retail displays. A recommended planting density of 40,000–50,000 plants per hectare ensures optimal space for vegetative growth, preventing inter-plant competition and guaranteeing a uniform, high-quality harvest.

Defense Mechanisms and Disease Resistance

The genetic background of Reyma RZ F1 includes robust resistance to pathogens that are critical for cabbage cultivation. Resistance to cladosporium, powdery mildew, and cucumber mosaic virus significantly minimizes the necessity for fungicide treatments during the early developmental stages. This immune package effectively protects the plant's resources, allowing them to be directed towards head formation rather than combating infection pressures.

Practical Recommendations

This hybrid is highly recommended for commercial farms targeting the fresh produce market. Due to its rapid growth dynamics and compact size, Reyma RZ F1 delivers predictable results when standard planting densities are maintained. The specific growth habit allows the heads to fill uniformly while retaining the tender leaf texture, which is highly valued by consumers in the premium early-season salad segment.
