Variety description

10 August 2026

The variety belongs to the Chinese cabbage Brassica rapa subsp. pekinensis. There is conflicting information regarding maturity timing: some sources characterize it as a variety with an average head formation period, while others indicate extra-early timing with a vegetation period of about 55 days.

Detailed agronomic characteristics, including morphological traits, yield indicators, and data on disease resistance, are absent from open scientific publications and registries. The variety name may indicate the presence of genetic resistance to viral diseases or white rust, but documented confirmation of these properties is missing.
