Sweet pepper TRIROSSO F1 is a medium-early indeterminate hybrid developed by the Dutch company Rijk Zwaan. The plant is characterized by its strength, robust root and leaf systems, and high growth energy. It is evenly laden with fruit and abundantly branched, promoting stable yield formation. The hybrid is resistant to stressful conditions, quickly recovers from adverse effects, and exhibits high resistance to viral and bacterial diseases, including bacterial spot, potato Y-virus, and tobacco mosaic virus. TRIROSSO fruits have a cube-shaped form with four chambers, distinguished by uniformity and attractive appearance. In technical maturity, they are dark green, and in biological maturity, they turn bright red. Fruit size varies: length ranges from 9 to 15 cm, diameter is about 6 cm, and wall thickness reaches 7-9 mm. The flesh is juicy, sweet, crisp, with high dry matter and sugar content, ensuring excellent flavor. The average weight of ripe fruit is 100 to 130 grams. Due to dense walls and quality flesh, the fruits withstand transportation and long-term storage, preserving their commercial and nutritional properties. TRIROSSO F1 hybrid is successfully grown both in greenhouses and open ground. Recommended planting density under film is 3 plants per square meter, and in open ground — 30,000 to 35,000 plants per hectare. The pepper is intended for fresh market sale and is suitable for processing, drying, and freezing. Thanks to its characteristics and disease resistance, this hybrid belongs to the best varieties, specifically selected for large supermarkets and commercial cultivation.
