Variety description

10 August 2026

The variety belongs to the white asparagus type. During international trials, the variety demonstrated stable yield indicators and produced a high proportion of marketable spears with a caliber of 7–17 mm. Research was conducted on spear storage, including antioxidant degradation processes and weight loss during freezing and cold storage.

Agronomic trials of the variety were conducted under irrigation conditions on sandy soils to evaluate the response to water consumption. Data on genetic resistance to diseases, precise plant height parameters, and maturity group are not detailed in open publications.
