Marquette F1 onion is a mid-season hybrid variety intended for cultivation in open and protected ground, including polyethylene and glass greenhouses. The maturation period is approximately 115 days, allowing harvest within one season. The bulbs have a round-cube shape, exhibit high density and uniformity, with a mass ranging from 130 to 300 grams, with individual specimens reaching up to 800 grams. The outer scale is dark bronze-colored, and the flesh is tender white. The plant is vigorous with a strong root system, ensuring good resistance to adverse weather conditions and stress. The Marquette F1 hybrid possesses high plasticity and adaptability, enabling the formation of marketable yields even under suboptimal growing conditions. It is resistant to diseases such as basal fusarium rot, false powdery mildew, and root rot, significantly reducing the risk of yield loss. Due to its high scale retention and good storability, the onion maintains its marketable appearance and quality for an extended period, making it particularly attractive for mechanized harvesting and long-term storage. Marquette F1 is recommended for direct sowing with a seeding rate of approximately 1 million seeds per hectare and a planting depth of about 3 cm. It is ideal for fresh consumption, processing, and sale on fresh markets, including use in salads. Due to its characteristics and resistance, this hybrid is widely used in Ukraine and Moldova, ensuring a stable and high-quality yield.
