Advances in apomixis of genus {\sl Paspalum}

Genus Paspalum, a perennial or annual grass of Gramineae, is one of the with great economic value groups. The gneus Paspalum includes many complex species and most of them are polypoloid. Due to the causes such as polyploidy and self-incompatibility, the plants of Paspalum, with the greatest number of apomictic species, show much complex and various reproduction characteristics. In this paper, a list of apomitic species of Paspalum is given. The cytological and embryological bases, and the characters of apomixis are described. Advances ingenetics and molecular biology of apomixis are in Paspalum also reviewed.
