摘要： 综述了近年来植物远缘杂交受精后生殖障碍的研究进展,对胚降解和杂种不育的特征特性与产生机理进行了分析;重点阐述了克服植物远缘杂交受精后生殖障碍的方法,包括幼胚拯救(子房、胚珠和胚培养)以克服胚败育、染色体加倍以克服杂种不育及化学处理、回交等其他方法;最后指出利用蛋白质组学技术并整合分子生物学研究手段,以阐明胚胎败育的分子机理,应是未来植物远缘杂交研究的重点方向。

Abstract: The research progress of distant hybridization in the field of plants breeding in recent years was reviewed comprehensively. The characteristics and mechanisms of post, ertilization barriers were analyzed on the view of embryo abortion and hybrid sterility. Meanwhile,the effective methods to overcome these barriers were mainly reviewed,including embryo rescue ( Ovary ovule and embryo culture) to prohibit its abortion to restore its fertility and other methods such as chemical treating and back}rossing. At last,doubling chromosomes,the future research emphasis in this field was suggested as revealing the molecular mechanism of embryo abortion in distant hybridization by using the proteomics combined with molecular physiological methods.

Key words: Distant hybridization, Reproductive barrier, Post-fertilization barrier, Embryo abortion, Hybrid sterility
