Assessing Polyembryony among Jamun (Syzygium cumini Skeels.) Collections

Jamun (Syzygium cumini Skeels.) is an important indigenous fruit of India. It belongs to the family Myrtaceae. It is native to India and Myanmar, however, it has naturalized throughout the South East Asia and Pacific regions. Polyembryony is a condition in which multiple embryos arise within the embryo sac by budding or by cleavage of the zygotic pro-embryo or from the synergids and antipodal cells (Maheswari and Sacher, 1963). Adventitious embryos are initiated directly from the maternal nucellar tissue, which surround the embryo sac containing a developing zygotic embryo (Aleza et al., 2010). This phenomenon is more common in gymnosperms (Ensign, 1919). Polyembryony is a common phenomenon in number of fruit crops like Mango, Citrus, Jamun and so on.
