Abstract: Autotetraploid rice is a new germplasm, in which two sets of genome are brought together into the same nucleus by chromosome doubling. It may be a useful material in breeding because of larger seed size and high potentiality in growth. Rice (Oryza sativa L.) consists of two subspecies, i.e. indica a

Key words: Intersubspecific hybrids in autotetraploid rice, Embryo sac, Fertilization, Confocal laser scanning microscopy（CLSM）
