%X Advance in polyembryonic seedling (PS) in angiosperms is summarized in the paper. There are many kinds of PS materials in angiosperms, but the PS materials from the special polyembryoes are only thought to be valuable in fixing the crop heterosis. However, affirmative conclusion about the mechanism of producing the PS material in angiosperms is not still formed and obtained. The haploid, diploid and polyploid PS materials have respectively special value in crop breeding.
