Abstract: Apomixis is an asexual propagation through seeds in which embryo is formed without the nuclear fusion of male and female gametes. Since some resultant seeds of apomixis are clones of their maternal parent, they are identical to their maternal parent in genotype. Therefore, apomixis could be used in the fixation of heterosis. Apomixes has abundant potential application values, however, the mechanism for apomictic formation is very complicated, which was represented by multi-forms of apomixis that are controlled by varied pathways, the complicated genetic mechanism that has not been determined and finalized, and diverse methods of studying it. In recent years, apomixis has been studied in terms of linkage analysis. This paper outlines research progress on apomixis, aiming at providing references for in-depth study.

Key words: apomixis, genetic control, epigenetics
