An influence of epimutagen 5-azacitidine on a flower stalk morphogenesis in sugar beet was studied. After the epimutagene treatment the great number of the first- and the third-order branch formation was observed. A higher level of branching completely modified the flower stalk architectonics (generations A0Az0 and A1Az1). A number of the second-order branches in the control and the experimental plants were not distinguished. A new epiphenotype with higher level of branching (generation A0Az0) inherited in daughter generation A1Az1. A flower stalk architectonics was modified because the third-order branches developed in the bract axil instead of flower primordium. A great number of lateral shoot modified a metamer organization of the flower stalk. The metamers on the third-order branches were single-flowered.
