Stefania

High-Yielding Large-Fruited Selection for Greenhouses

The «Stefania» tomato variety, developed by the Federal Scientific Center for Vegetable Production, is engineered for professional greenhouse cultivation. As a mid-to-late maturing variety (120–130 days), it is specifically bred to deliver a substantial yield with individual fruits consistently exceeding 200 grams.

Operational Guidelines for Growers

The flat-round shape and vibrant pink skin make this variety a strong competitor in the fresh produce market. With more than six seed chambers, the fruit offers a firm, fleshy texture that maintains integrity during handling and transport, provided the logistical chain is well-managed.

• Plant Management: Given its large fruit size, trellising and regular pruning are mandatory. Aim for a density of 2-3 plants per square meter to ensure adequate airflow and prevent fungal issues common in dense greenhouse environments.
• Nutrient Strategy: Because of the long vegetation period and large fruit weight, the plants require a robust potassium-based fertilization program during the fruit-set phase. This prevents hollow fruit and ensures consistent filling.
• Market Application: «Stefania» is positioned as a premium "salad tomato." Its thin skin and rich flavor profile are best suited for immediate sale at retail outlets or farmers' markets rather than long-term storage.

For growers looking to diversify their lineup with reliable, large-sized pink tomatoes, «Stefania» offers the necessary genetic potential. It requires diligent adherence to irrigation and support protocols, rewarding the grower with substantial, marketable produce that meets consumer demand for quality pink-fleshed varieties.
