Environment F1 — early indeterminate tomato hybrid, intended for cultivation in plastic greenhouses and under plastic coverings. The period from emergence to the start of ripening is 85-95 days, allowing harvest in the first and second cropping cycles. The plant is vigorous, with a well-developed root system, well-adapted to limited substrate volume. Leaves are dark green, medium to large in size, with a drooping arrangement. The first flower cluster forms above the 10th-12th leaf, subsequent clusters appear every three leaves. Flowers are simple, containing 5 to 8 fruits, with the possibility of intermediate flower types at high temperatures. Fruits of Environment F1 are flat-round, firm, with a shape index of 0.8-0.9, average weight of 280-300 grams. In technical ripeness, they are green without spots, and in biological ripeness — deep pink. Tomatoes have high flavor qualities and good transportability, resistant to cracking and blossom end rot. Yield of the hybrid reaches 9.5-11 kg per square meter, making it attractive for commercial cultivation. The hybrid is highly resistant to major tomato diseases, including mosaic virus, verticillium wilt, fusarium wilt, and cladosporiosis. Moderate resistance is noted to bacterial spot. Thanks to these characteristics and its ability to set fruit well even under stressful conditions, Environment F1 is a reliable choice for obtaining early and high-quality tomato harvests for fresh consumption.
