Microspores were cultured on the modified B5 liquid medium containing 2.4D (0.1 mg L?1), NAA (0.1 mg L?1), L-glutamine (500 mg L?1), L-serine (100 mg L?1), and sucrose (100 g L?1). The developmental stages of microspores and divisions were observed. Initially, the formation of binuclear and multicellular structures was noticed. Plants regenerated in the cultures in which the tetrad stage of microsporogenesis had predominated. Embryoids were still forming 24 weeks after the cultures were set up. Six weeks after the transfer of androgenetic embryos onto the B5 regeneration medium, they were converted into complete plants. Out of 90 androgenetic plants planted in a growth chamber, 42 plants adapted to the new conditions. All of those plants proved to be diploids in cytometric analysis.
