Rafaela F1

Technical Profile of «Rafaela F1» by Semo

Czech breeding house Semo is known for a pragmatic approach to vegetable genetics, and the «Rafaela F1» hybrid is a prime example. This early-maturing, conical-type pepper focuses on yield stability in both open-field conditions and controlled environments. With a growing cycle of 55–65 days, it fits into the «fast-track» category, which is vital for market segments prioritizing early output.

Fruit Architecture and Marketability

The core of this hybrid’s physiology is its color transition and geometry. Technical maturity (dark green) allows for early harvesting, while the full biological potential is realized upon reaching a deep red hue. The conical shape facilitates logistics and packaging, reducing damage rates during transport. With a wall thickness of 4-5 mm, the hybrid maintains a balance between juiciness and density, making it versatile for both the fresh produce market and processing.

Phytopathological Resistance

A major challenge for conical peppers is vulnerability to viral infections. Semo engineers have integrated comprehensive resistance into «Rafaela F1» against:

• Tobacco Mosaic Virus (TMV);
• Various viral mosaic diseases that typically reduce photosynthetic leaf area.

This genetic defense reduces the reliance on heavy fungicide applications, allowing the agronomist to focus on mineral nutrition management rather than emergency field intervention.

Practical Insights for the Agronomist

The hybrid adapts well to temperature fluctuations in glasshouses and tunnels, successfully retaining fruit set even under stress factors. The consistent 4-5 mm wall thickness combined with rapid maturation makes this variety a highly effective tool for continuous, multi-stage production cycles.
