QUATRO F1 — a medium-maturing indeterminate tomato hybrid, maturing in 100-115 days from germination. It is intended for cultivation in extended-cycle glasshouses and protected soil, enabling a stable yield under various conditions. Plants are robust, vegetative, well-balanced, and well-branched, with leaves ranging from medium to large size, dark green in color. The first flower cluster forms above the 10-11th leaf, subsequent clusters every three leaves, each cluster simple and containing 4-6 fruits. QUATRO F1 fruits are flat-round with a shape index of 0.8-0.85, slightly ribbed at the peduncle, firm, and possess good transportability. In technical ripeness, they are intensely green without spots at the base, and in biological ripeness — deep red. Average fruit weight is 220-240 grams. For larger fruits, it is recommended to regulate: first truss with 3 fruits, next 2-3 trusses with 4 fruits, and above — 4-5 fruits. The hybrid exhibits high resistance to tomato mosaic virus, fusarium, and cladosporeiosis, ensuring reliability and stable yield. Additionally, QUATRO F1 demonstrates excellent fruit set even in hot months, making it a profitable choice for greenhouse cultivation. The root system develops well on various substrates, including coconut and mineral wool, expanding cultivation agronomic possibilities.
