Troy F1 onion is an early-maturing hybrid winter onion variety of Dutch origin, characterized by high yield and versatility. The maturation period ranges from 60 to 75 days from emergence to mass leaf fall. The bulbs are round or flat-round, weighing 80 to 120 grams, with outer dry scales ranging from yellow to brown, while the inner part is white and juicy. Dry matter content in bulbs is about 14.5%, providing firmness and moderate sweetness. The flavor is semi-pungent and moderately sharp, making it suitable for cooking, preservation, and salads.
A distinctive feature of this variety is intensive branching of cylindrical leaves, 20 to 45 cm long, with a characteristic waxy coating. Troy F1 exhibits high resistance to bolting and diseases, as well as good cold tolerance. Due to its dense dry scales, harvest can be mechanized. Recommended to sow as winter or spring planting, with optimal planting density of 10 cm between plants and 20 cm between rows, at a depth of 6–10 cm for winter sowing.
The Troy F1 variety is adapted to various soil types, but performs best on well-drained loams enriched with organic matter. With proper agronomy, yield can reach up to 5 kg per square meter, and storage period lasts 3 to 6 months without loss of flavor or quality. Troy F1 is rich in B-vitamins and contains elevated levels of iron, calcium, and potassium, making it not only tasty but also nutritious.
