Onion Airoso

Genetics and Pathogen Resistance

The «Airoso» onion hybrid from Nunhems is engineered for durability and high-yield potential in challenging soil conditions. The primary technical advantage is its high genetic resistance to Fusarium and basal rot, which are notorious for causing field losses. By focusing on these specific resistance traits, Nunhems has provided a cultivar that maintains crop health even under high-humidity conditions or periods of extreme heat, ensuring a cleaner harvest with minimal pre-harvest decay.

Morphology and Growth Metrics

With a vegetation period of 120–130 days, Airoso demonstrates consistent bulb development. The bulbs reach an average mass of 200–250 grams, showcasing a uniform, rounded shape. The outer scales are a vibrant brown, providing a robust, protective barrier that survives mechanical harvesting, sorting, and long-distance logistics without bruising or cracking.

Storage Technology and Quality

Inside, the bulb features a crisp, white flesh. However, the most significant value proposition for growers is its exceptional storage capability. Airoso can be stored for 9–10 months while maintaining its internal density and structural integrity. This longevity allows farmers to bypass harvest-time price volatility and supply the market until late spring with consistently high-quality, shelf-ready produce.
