Variety description

10 August 2026

The Hystar F1 hybrid belongs to the Rijnsburger cultivar group. Scientific studies show that this onion contains a lower amount of certain aromatic compounds, such as 2-methyl-2-pentenal, in comparison to a number of other varieties.

The variety demonstrates moderate to high resistance to Fusarium basal rot. Research confirms that testing results at the seedling stage are a reliable indicator of resistance in mature bulbs.

The hybrid is frequently used as a reference sample for comparison in agronomic and physiological experiments, including metabolomic analysis and the study of bulb dormancy mechanisms.
