Variety description

10 August 2026

The hybrid forms a tall plant with a powerful root system and developed foliage. The vegetation period is 85–95 days from emergence. The bulbs have a regular round shape, are dense, with pearly-white outer scales and juicy snow-white flesh. The mass of a marketable bulb is on average 120–250 g; under favorable conditions, the fruits can reach 800 g.

The taste of the onion is semi-pungent, moderately sweet, without bitterness. The variety is intended for fresh consumption and short-term storage for a period of 4–6 months. The hybrid has resistance to pink root rot, Fusarium basal rot, and downy mildew, and is also tolerant to bolting. Not suitable for mechanical harvesting.

Cultivation is possible by seedling method or direct sowing in open field with a seeding rate of about 1 million plants per hectare. In a number of sources, the hybrid is identified with the Super Star variety.
