ABSTRACT
Generally a seed contains a single embryo which geminates into a seedling, however, in some angiospermic family multiple embryos are developed in an individual seed and consequently multiple seedlings are produced which is known as polyembryony, whereas the term ‘monoembryony’ has been used to refer to a single seed that contains one embryo to describe strictly sexual seed parents. Thus polyembryony is the occurrence of two or more embryos in a developing ovule and the additional embryos result from the differentiation and development of various maternal and zygotic tissues associated with the ovule of the seed (Tisserat et al. 1979).
