Abstract: In this paper, immature embryos in bread wheat (Triticum aestivum L.) were cultured to investigate ways of organ development. The results show that not only adventitious buds and roots, also complete plantlets are produced in the culture. Both the adventitious buds and complete plantlets are derived from meristems of compact or pellet-like calli. The characters of organ development and growth between somatic embryo and organ regeneration ways are compared. It suggests that the organs of immature embryo culture are developed from the dual systems including the main way of somatic embryo and the accompanying way of organ regeneration in wheat.

Key words: Triticum aestivum, immature embryo culture, organ development, histomorphology
