This short-day hybrid, engineered in the Netherlands, has earned a reputation for reliability and consistent performance, delivering high-quality, market-ready bulbs that meet modern retail standards.

Agronomic Profile and Market Value

The primary appeal of the Wolf F1 lies in its uniformity. It produces firm, round bulbs weighing between 140–150 grams, covered in a signature bright-brown skin. Its interior, a crisp white flesh, classifies it as a premium salad onion, favored by consumers for its mild, non-pungent flavor profile.

• Maturation Period: 260–270 days, necessitating precise planting schedules.

The hybrid is designed specifically for manual harvesting. At recommended planting densities, the plant develops a robust foliage system, which simplifies field operations during the peak season. Its genetic background from Nickerson Zwaan ensures high seed vigor and synchronized maturity, reducing labor costs associated with harvesting and sorting.
