Variety description

10 August 2026

The variety belongs to the Virginia type and is intended for cultivation in the conditions of Northern Bulgaria. During multi-year trials, it showed stability of morphological traits and a significant superiority in dry tobacco yield over the Virginia Kocker-254 standard.

The plant demonstrates an accelerated onset of technical leaf maturity. The number of leaves on the stem in certain observation periods exceeded the indicators of the compared standard variety. The variety is an example of the successful application of haploid technology in tobacco breeding.
