SUMMARY. The regeneration method of the commercial line Bn1 winter rape was optimized. Hypocotyls fragments of 6-day-old seedlings were used as explants. Regeneration occurred by organogenesis on a MS nutrient medium supplemented with 3 mg/L of benzylaminopurine and 2 mg/L of 2-isopentyladenine. All obtained regenerant plants were successfully rooted in a hormone-free nutrient medium and adapted to soil conditions. The selected vernalization conditions provided 83,93 5,33 % of budding and flowering. PCR analysis using ISSR 2 and ISSR 15 markers showed that somaclonal variation does not occur in winter rape of the Bn1 line while using the proposed technique. Thus, the developed system is effective and economically viable for producing of biotechnological winter rape plants.

Key words: winter rape, regeneration, organogenesis, growth regulators, vernalization, somaclonal variation
