【Abstract】 Apomixis differs from sexual reproduction in its production of seed without nuclear fusion. Diplospory, generative aposporp and adventive embryony are the three kinds of apomixis capable of main taining the hybrid vigor of F1. The genetic characteristics of the generation of haploid androgenesis are stable, hence it has potential value in breeding.更多还原
