This is a review on apomixis in plant.Plant apomixis that is a new growing tip of biology possesses important significance in fixation of heterosis,shortening breeding period.A good progress is made in reseach of transfer of genes controling apomixis from wild to related cultivated species and use of these genes in plant breeding is possible.The embryology of apomixis has been studied with the paraffin sectioning methods,but now with interference\|contrast micoscopy intact cleared overies or immunohistochemical technique.Megasporogenesis of dislospory characterized by the nuclear assuming a bell\|bar shape and the lack of callose deposition within and about the cell walls of the megaspore mother cell (MMC).Molecular markers of apomixis in Pennisetum and Tripsaum have been found and the latter is located on the distal end of the long arm of chromosome 6.\;
