The 4K20 hybrid, known by the commercial name Annalisa, is a specialized variety developed for cultivation in conditions requiring protection against specific soil pathogens. The main characteristic of the variety is its nematode resistance (NT-variety) to the beet cyst nematode.
During the mid-2000s, the variety underwent yield and disease resistance testing in comparative studies. Data on current morphological traits and quality indicators of the variety are absent in current sources, as the hybrid is not part of the modern market portfolio.
