In vitro culture of shoot apical meristems of Helianthus annuus was studied to determine the cytological condition of calli and regenerated shoots. A broad chromosome mosaicism (aneusomary) in bath callus and regenerated shoots was found, reflecting the cytological conditions of the explain. During in vitro plant development, a diplontic selection took place that was more rapid when very precocious in vitro flowering occurred.
