Red onion Countach F1 — a medium-maturing hybrid of red long-day onion with a maturation period of 115-120 days. The bulbs have uniform spherical shape, diameter from 60 to 100 mm, and weight from 150 g and more. Their rich red-violet color and dense skin provide an attractive appearance and make the onion in demand both in domestic markets and for export. Thanks to its dense flesh and skin structure, Countach F1 onion has excellent storability and can be stored for 6 to 9 months, preserving its flavor and appearance. The hybrid exhibits medium resistance to fungal diseases such as root rot and fusarium wilt, enhancing crop reliability. Recommended planting density is 800-900 thousand plants per hectare, which is optimal for mechanized harvest and high yield. Countach F1 adapts well to cultivation both in open ground and in greenhouses, preferring medium-heavy soils with pH no higher than 7.5. Best preceding crops for this culture are potatoes, cabbage, and legumes. Irrigation should be moderate and applied at the root level; irrigation should be stopped several days before harvest to improve flavor and appearance of bulbs. Countach F1 has a sweet-spicy flavor and can be used both fresh and after heat treatment, including canning and preparation of various dishes. Its dense flesh and vibrant color make this variety popular among consumers, and its high uniformity and resistance to damage during transport allow large-scale transportation over long distances. The hybrid is produced in the Netherlands by Nunhems, ensuring high seed quality and stable yield.
